DESCRIPTION
LT7182S
Dual Channel 6A, 20V, PolyPhase
Step-Down Silent Switcher with Digital
Power System Management
Demonstration Circuit 2836A is a dual-output PolyPhase
®
DC/DC synchronous step-down regulator with 4V to 20V
input range featuring LT
®
7182S. Each output can sup-
ply 6A continuous/9A maximum transient load current.
LT7182S is a dual 6A monolithic step-down regulator.
The second-generation Silent Switcher
®
structure is
incorporated into LT7182S to minimize EMI and reduce
PCB layout sensitivity. It also integrates digital power sys-
tem management function allowing for programmability
and telemetry with a PMBus/I2C compliant serial inter-
face. Please see LT7182S data sheet for more detailed
information.
The demonstration circuit 2836A runs at 1MHz to mini-
mize solution size. The peak efficiency at 12V input is
83.2% for 1.2V rail and 91.1% for 3.3V rail. The IC tem-
perature rise is 70°C when both channels run at full load,
6A each, at 1MHz.
The demo board has EMI filters installed for both chan-
nels. The conducted and radiated EMI performances of
the board (with EMI filters) are shown in Figure2. The red
lines in Figure2 are CISPR25 CLASS 5 limit.

PERFORMANCE SUMMARY
DC2836A powers up to default settings and produces
power based on configuration resistors without the need
for any serial bus communication. This allows easy evalu-
ation of the DC/DC converter. To fully explore the power
system management features of the part, download the
GUI software LTpowerPlay
®
onto your PC and use ADI’s
I2C/SMBus/PMBus dongle DC1613A to connect to the
board. LTpowerPlay allows the user to reconfigure the part
on the fly and store the configuration in EEPROM, view
telemetry of voltage, current, temperature and fault status.
GUI Download
The software can be downloaded from: LTpowerPlay
The LT7182S data sheet gives a complete description of
the part, operation and application information. The data
sheet must be read in conjunction with this demo manual
for DC2836A.
For more details and instructions of LTpowerPlay, please
refer to LTpowerPlay GUI for LT7182S Quick Start Guide.

QUICK START PROCEDURE
DC2836A is easy to set up to evaluate the performance of
the LT7182S. Refer to Figure3 for proper measurement
equipment setup and follow the procedure below:
NOTE:When measuring the input or output voltage ripple,
care must be taken to avoid a long ground lead on the
oscilloscope probe. See Figure5 for the proper scope
technique.
1. Set an input power supply that is capable of 20V/18A.
Then turn off the supply.
2. With power off, connect the supply to the input termi-
nals VEMI and GND. Set default jumper position:SW1:
ON; SW2: ON
3. Turn on the power at the input.
NOTE:Make sure that the input voltage never exceeds 20V.
4. Check for the proper output voltages of 1.2V ±0.5%
(1.194V ~ 1.206V) and 3.3V ±0.5% (3.283V ~ 3.317V).
Turn off the power at the input.
5. Once the proper output voltage is established, connect
variable loads capable of sinking 6A at 1.2V and 3.3V
to the output terminals VOUT0/VOUT1 and GND. Set
the current for 0A.
a. If efficiency measurements are desired, ammeters
can be put in series with the output loads to measure
the DC2836A’s output currents.
b. Voltmeters can be placed across the output termi-
nals to get accurate output voltage measurements.
6. Turn on the power at the input.
NOTE: If there is no output, temporarily disconnect the
load to make sure that the load is not set too high.
7. Once the proper output voltages are established again,
adjust the load and/or input within the operating range
and observe the output voltage regulation, ripple volt-
age, efficiency and other desired parameters.
8. Connect the dongle and control the output voltages
from the GUI. See LTpowerPlay GUI for the LT7182S
Quick Start Guide for details.
NOTE: When measuring the output or input voltage rip-
ple, do not use the long ground lead on the oscilloscope
probe. See Figure4 for the proper scope probe technique.
Short, stiff leads need to be soldered to the (+) and (–)
terminals of an output capacitor. The probe’s ground ring
needs to touch the (–) lead and the probe tip needs to
touch the (+) lead.

LTpowerPlay SOFTWARE GUI
LTpowerPlay is a powerful Windows based development
environment that supports Linear Technology power sys-
tem management ICs and μModules. The software sup-
ports a variety of different tasks. You can use LTpowerPlay
to evaluate Linear Technology ICs by connecting to a
demo board system. LTpowerPlay can also be used in an
offline mode (with no hardware present) in order to build a
multichip configuration file that can be saved and reloaded
at a later time. LTpowerPlay provides unprecedented diag-
nostic and debug features. It becomes a valuable diagnos-
tic tool during board bring-up to program or tweak the
power management scheme in a system, or to diagnose
power issues when bringing up rails. LTpowerPlay utilizes
the DC1613A USB-to-SMBus controller to communicate
with one of many potential demo system, or a customer
board. The software also provides an automatic update
feature to keep the software current with the latest set
of device drivers and documentation. The LTpowerPlay
software can be downloaded from:
LTpowerPlay | Analog Devices
To access technical support documents for LTC Digital
Power Products visit the LTpowerPlay Help menu. Online
help also available through the LTpowerPlay.

LTpowerPlay QUICK START PROCEDURE
The following procedure describes how to use LTpowerPlay
to monitor and change the settings of LT7182S.
1. Download and install the LTPowerPlay GUI:
LTpowerPlay | Analog Devices
2. Launch the LTpowerPlay GUI.
a. The GUI should automatically identify the DC2836A.
The system tree on the left hand side should look
like this:
b. A green message box shows for a few seconds in
the lower left hand corner, confirming that LT7182S
is communicating:
c. In the Toolbar, click the R (RAM to PC) icon to read
the RAM from the LT7182S. This reads the configu-
ration from the RAM of LT7182S and loads it into
the GUI.
d. If you want to change the output voltage to a differ-
ent value, like 1.5V. In the Config tab, type in 1.5 in
the VOUT_COMMAND box, like this:
Then, click the W (PC to RAM) icon to write these reg-
ister values to the LT7182S. After finishing this step,
you will see the output voltage will change to 1.5V.
If the write is successful, you will see the following
message:
e. You can save the changes into the NVM. In the tool
bar, click RAM to NVM button, as following
f. Save the demo board configuration to a (*.proj) file.
Click the Save icon and save the file. Name it what-
ever you want.
