USAGE GUIDE
This evaluation board is designed to demonstrate the
performance and functionality of the IDTP95020 in a lab
bench test environment. In most cases, this board can be
wired into an existing system for evaluation. For complex
or electrically sensitive situations, it is recommended to
use the reference layout to integrate this design into your
system to eliminate hardware limitations or signal
degradation introduced by long leads.
With no inputs, this device can function in its pre-
programmed mode of operation using battery power with
limited flexibility to change modes using hardware
switches. To evaluate the full potential of this device an
AC adapter input and PC with USB output is required.
Everything you need (except the PC) is included in this
evaluation kit.
Quick-Start Guide
Follow these simple steps to power-up and enable the
power management features of the IDP95020:
1. Connect the USB cable from PC to the
IDTP95020-EVAL board
2. When prompted, install the USB software drivers
(first time only)
3. Plug the AC adapter into the wall (120 VAC) and
connect the other end (4.5 VDC) into the adapter
plug on the IDTP95020-EVAL board.
4. Open the CyrusTool to change register settings
and control the device.
Verifying Connectivity
You can verify that the IDTP95020 is properly connected
to your computer and able to communicate to the
evaluation board by reading the global register setting.
After you open the CyrusTool program, click the ‘Read’
button on the opening screen. You should see the ‘Value’
field read 0x55 and there should be no error messages. If
this is what you see, then your connection is ready.

All of these factory settings can be controlled by changing
the register settings of the device while in operation, or by
modifying the script file that is loaded into the EEPROM.
Installing the Software Drivers
The first time that you use the IDTP95020-EVAL board,
you must install the drivers to communicate with the USB
to I2C controller that is located on the evaluation board.
The purpose of this controller is to take instructions from
the IDTP95020 software tool through the USB connection
and convert those instructions to I2C for communication
with the IDTP95020 device.
To install the driver, open the IDTP95020-EVAL CD and
run the file: /Software/Drivers/CDM 2.04.06.exe. This
will install the drivers automatically. After the installation
process is complete, you may connect the evaluation
board to the computer with the USB cable and use the
software tool.
Running a TCL Script File
TCL script files are used to modify the embedded
microcontroller and register settings while the IDTP95020
is in operation. The IDTP95020-EVAL CD contains some
useful scripts to demonstrate some features and
functionality of the IDTP95020 device. To run a script file,
do the following:
1. Connect the USB cable, open the CyrusTool and
navigate to the ‘TCL Script’ tab
2. Click the ‘Add Scripts’ button to choose the script
file
3. Click the ‘Run’ button to load the script

Creating a Custom Power-On
Sequence
The IDTP95020 has the flexibility to run any custom
power-on sequence to suit the special needs of your
system. The IDTP95020-EVAL CD includes the CyrusTool
which will enable you to generate a custom power-on
sequence script file using a graphical user interface (GUI).
To create your own power-on sequence, follow these
steps:
1. Connect the USB cable, open the CyrusTool and
navigate to the ‘Power On Sequence’ tab
2. Add the elements for the voltages and power-on
time delays that you desire
3. Save the script file to a known location
4. Follow-steps to “Programming the EEPROM
Script” as described in this document
Figure 7. Power On Sequence Tab
Setting the Voltages and Time Delays
Each regulator’s output in a power on sequence must
have a specified output voltage and time delay. The graph
on the left side depicts each regulator as a red circle. The
Y-axis is the output voltage level and the X-axis is the time
delay from when power is first applied to the device.
Choose the first regulator that you want to use from the
‘Element:’ drop down menu on the left and press the ‘Add’
button. This will place the red circle on the graph. You can
then drag the circle to the output voltage and time delay
that is desired. Alternatively, you can choose the specific
voltage and time delay from the drop down menu and
input field on the right side. In this case, when the ‘Add’
button is pressed, the red circle will be placed as specified
and not require any further modification.
Follow this process until you have configured all of the
regulators that you want to turn on when power is first
applied to the device.
Figure 8. Power On Sequence Showing 9 Regulators
Saving and Loading Your Power On Sequence Script
After you have configured the power on sequence as
desired, press the ‘Save As’ button and choose the
location to save your new script file.
Figure 9. Saving the Power On Sequence
Now that you have created and saved your own custom
power on sequence script, you must load it into the
EEPROM so that the IDTP95020 device can access it
when power is applied. To do this, follow the instructions
in the “Programming the EEPROM Script” section.

IDTP95020-EVAL
Evaluation Board Manual
December 13, 2010 7
Programming the EEPROM Script
The IDTP95020-EVAL is equipped with an EEPROM chip
that stores an initial start-up script that the IDTP95020
device loads at start-up. In a typical application, the
IDTP95020 is configured by the application processor or
can be mask programmed with a custom script inside the
IDTP95020 device itself.
It is possible to change the default programming of the
EEPROM using the IDTP95020 software tool. To load a
new script, follow these steps:
1. Change the EEPROM hardware switch to the
‘Write EEPROM’ position
2. Connect the USB cable, open the CyrusTool and
navigate to the ‘EEPROM Access’ tab
3. Choose the input script file location
4. Choose where to store the binary output file
5. Generate by the binary output file
6. Download the binary file to the EEPROM
7. Return the EEPROM hardware switch back to
the ‘Read EEPROM’ position
8. Reset power to the evaluation board
Change Hardware Switch to ‘Write EEPROM’
There is a hardware EEPROM switch on the evaluation
board to select whether the EEPROM should be wired to
the USB-I2C chip, or to the IDTP95020 device. In the
‘Write EEPROM’ position, the EEPROM device can be
accessed by an external control, such as the computer. In
the ‘Read EEPROM’ position, the IDTP95020 device can
load the start-up script during start-up or reset. Thus, you
must manually slide the hardware switch to the ‘Write
EEPROM’ position when attempting to modify the script
file that is loaded in the EEPROM.
Figure 10. EEPROM Hardware Switch to Write Mode
Navigate to the EEPROM Access Tab
Open the ‘CyrusTool.exe’ file located on the CD in the
/Software directory and navigate to the ‘EEPROM Access’
tab. Make sure that the USB cable is connected from the
computer to the evaluation board. If it is not connected,
the program will alert “Device Not Found” and ask if you if
want to enter simulation mode. If this happens, choose
‘No’, connect the cable, and reopen the program.
Figure 11. Navigating to the EEPROM Access Tab

Evaluation Board Manual
December 13, 2010 8
Generating the Binary File
The EEPROM chip requires a binary (.BIN) file be loaded.
The IDTP95020 software tool has a function to convert
a .TXT script file into a .BIN file.
Put the location of the .TXT script file in the ‘Input File:’
field. Then, put the location where you want the .BIN file to
be stored after it is generated in the ‘Output File:’ field.
Finally, click the ‘Generate’ button to create the .BIN file.
Figure 12. Generating the Binary File
Figure 13. Success Message for Generating the Binary File
Downloading the Binary File to EEPROM
After creating the binary file, the software tool will assume
that you want to load the binary file that you just created,
and thus, automatically put the path of your new binary file
in the ‘File:’ field. If you want to use a different binary file,
you can choose a new path here.
Click the ‘Download’ button to download the file to the
EEPROM.

Change Hardware Switch to ‘Read EEPROM’
There is a hardware EEPROM switch on the evaluation
board to select whether the EEPROM should be wired to
the USB-I2C chip, or to the IDTP95020 device. In the
‘Write EEPROM’ position, the EEPROM device can be
accessed by an external control, such as the computer. In
the ‘Read EEPROM’ position, the IDTP95020 device can
load the start-up script during start-up or reset. Thus, you
must manually slide the hardware switch back to the
‘Read EEPROM’ position so that the IDTP95020 device
can load the new script at startup, as shown in Figure 16.
Figure 16. EEPROM Hardware Switch to Read Mode
Changing Register Settings
While there are several demonstration scripts included on
the IDTP95020-EVAL CD in the /Software/Scripts
directory, it is often useful to change the individual register
bits to further evaluate the capabilities of the IDTP95020
device. To change the register bits, follow these steps:
1. Connect the USB cable and open the CyrusTool.
By default, you will be in the ‘Register’ tab.
2. Select the ‘Register List’ of the block you want to
modify.
3. Click the ‘Detail’ button of the register you want
to modify.
4. Click the ‘Read’ button.
5. Change the bits as desired.
6. Click the ‘Write’ button.
Figure 17. Click the ‘Detail’ Button to Modify the Register Setting
Figure 18. Changing the Register Setting
After pressing the ‘Write’ button, your changes will take
effect immediately. To confirm that your changes were
applied, you can press the ‘Read’ button again. This will
read the register setting which should be the same as
what you just wrote.
For advanced users, you may also change the register
settings by entering the hexadecimal code into the
‘Settings’ field. Furthermore, you can do this from the
CyrusTool home screen by entering the register address
and hexadecimal code. This will eliminate the need to
navigate to the different registers.

Manually Enabling and Setting the DC DC Regulators
The five switching regulators and seven LDO regulators
have each have a global and local disable bit. Both bits
must be high for each regulator to be enabled.
For example, to enable the LDO_150_0 regulator check
the Global >> LDO_GLOBAL_EN register and make sure
that the LDO_150_0_EN bit is high (global enable).
Then, navigate to LDO >> LDO_150_0_VOUT and make
sure that the ENABLE bit is high (local enable).
At this same register, you can modify the other 7 bits to
change the output voltage. For example, for 2.5V output
setting enter 1000110b for bits [6:0].
Figure 19. LDO_150_0 2.5V Output Voltage Setting
Follow similar steps to enable and change the other buck
switching regulators Buck_500_0, Buck_500_1, and
Buck_1000. For example, modify the registers:
- Global >> DCDC_GLOBAL_EN
-DCDC >> BUCK_500_0_VOUT
External I2C Input Switch
This evaluation board provides three options to control the
IDTP95020 I2C: using your computer’s USB cable, an
external ribbon cable, or test points.
To control the device from an external source connected
to the ribbon cable or I2C test points, slide the switch down
to the ‘EXT I2C’ setting as shown in Figure 20.
Figure 20. External I2C Input Switch

IDTP95020-EVAL

Setting the Battery NTC Mode
There are three modes for the battery temperature
sensing (NTC) function.
NTC Charge ON
This mode will pull the CHRG_NTC pin low thus disabling
the temperature protection feature. In other words, the
battery charger will not be affected by temperature.
NTC Charge OFF
This mode will pull the CHRG_NTC to CHRG_VNTC, thus
mimicking a too-cold condition. This will shut down the
battery charger.
NTC Battery
This mode will use the actual battery NTC that is
connected to the NTC test point or NTC pin of the three-
pin battery connector.
Figure 21. Battery NTC Mode
Four-Switch Dip Switch
The four-switch dip switch offers control for the EX_ROM
pin, the VDDIO_CLK pin, and both hotswap channels.
EX_ROM Switch
This switch will pull the EX_ROM pin high or low. The
purpose is to choose whether the IDTP95020 device
should read the start-up script from its internal ROM, or
retrieve it from the external EEPROM chip. The default
setting for demonstration purposes is to put the switch in
position #1, ‘EXT’.
VDDIO_CLK Switch
This switch will choose where to connect the VDDIO_CLK
pin on the IDTP95020 device. Position #1 will use the
LDO_150_0 output as the supply. Position #2 will use the
fixed 1.8V supply.
HOTSWP #1 and HOTSWP #2 Switches
These switches toggle the HSCTRL1 and HSCTRL2 pins
on the IDTP95020 device. Position #1 will enable the
hotswap output. Position #2 will disable it. The supply
comes from Buck_500_0. The outputs are accessible by
the yellow hotswap test points on the right-top of the
evaluation board.
Figure 22. Four-Switch Dip Switch

Evaluation Board Manual
December 13, 2010 12
Clock Outputs
The IDTP95020 evaluation board has probe points for the
various clock signal outputs. Each of the five outputs have
a small probe-hole and larger through-hole for each signal
and ground. The small holes are used for probe points,
while the larger holes can be populated by a standard
10-pin ribbon connector.
Refer to the IDTP95020 datasheet for information to
enable and disable the various clock outputs.
Figure 23. Clock Outputs
AC to DC Wall Adapter
The AC to DC wall adapter has a dial to select the output
voltage. It is recommended to use the 4.5V setting for
most applications. At very high loads, it is possible that the
poor load regulation of the adapter may cause the voltage
at the board to be <4.2V, which will cause the IDTP95020
device to shutdown. In this case, it’s possible to use the
6V setting, but the on-board over-voltage protection (OVP)
chip may interfere.
If you need more input power, you may disconnect the
plug head from the AC adapter cable and use the two pins
to connect your power supply leads.
Figure 24. Recommended 4.5V Wall Adapter Setting
LED Backlight
The IDTP95020 is equipped with 20 white LEDs to
simulate an LED backlight application. To demonstrate
this feature, follow these steps:
1. Connect USB and Adapter to the board
2. Run the led_backlight_50.bin script
You will need to connect your USB cable so you can run
the led backlight script. The adapter is recommended to
provide the maximum power for the highest brightness
setting.
Run the script located on the IDTP95020 CD at location
/Software/Scripts/led_backlight_50.bin. This script will
program the LED backlight to 50% brightness. For 100%
brightness, use /Software/Scripts/led_backlight_100.bin.
Refer to the “Running a TCL Script File” section for more
details.
Manually Enabling and Setting the LED Backlight
As described in the “Changing Register Settings” section,
you can manually enable and program the LED Backlight
by changing the register settings. First, make sure the
Global Enable bit is high, then change the local enable bit
high. This will enable the LED backlight. To modify the
brightness, change the DCDC >> LED_BOOST_IOUT
register setting.

IDTP95020-EVAL
Evaluation Board Manual
December 13, 2010 13
Audio Output (CLASS_D)
The IDTP95020 will take an audio input from your PC (or
other audio source) and output that sound through the
CLASS_D audio amplifier to drive the 4Ωnotebook
speaker.
To use the CLASS_D audio amplifier, follow these steps:
1. Connect USB and Adapter to the board
2. Connect audio cable from PC to board
3. Connect audio cable from board to speaker
4. Run the audio_output_gain12.bin script
You will need to connect your USB cable so you can run
the audio script. The adapter is recommended to provide
the maximum power for the best audio performance.
Connect the 3.5mm audio cable from your PC’s audio
output port to the Line Level Input jack on the IDTP95020
evaluation board. Since the purpose of the CLASS_D is to
drive the output speaker, you can use any low-power input,
such as your portable MP3 player. Then, connect the
CLASS_D Output to the speaker using the other 3.5mm
audio cable. Refer to Figure 25 for an illustration.
Run the script located on the IDTP95020 CD at location
/Software/Scripts/audio_output_gain12.bin. Refer to
the “Running a TCL Script File” section for more details.
Headphones Output
After following the steps above, you may connect
headphones to the headphone jack located on the bottom-
left of the board. You will hear the audio output
simultaneously with the CLASS_D Output.
Line Level Output
After following the steps above, you may use the Line
Level Output as a repeater of your original input signal. It
is located on the left-bottom of the board. This is a low-
power output that can be connected to a different buffered
input.
