registers, for output voltage and operation mode control.
Key Features
• Small, compact design
•I
2C interface for programmable VOUT, slew rate and various operation modes (Forced Bypass, Auto-PFM,
Forced PWM)
• Connectors, test points, and jumpers for easy probing

1. Functional Description
The ISL9122AIIN-EVZ and ISL9122AIRN-EVZ evaluation boards provide a simple platform to evaluate the
feature-rich ISL9122A buck-boost regulator. Both boards have a 3.3V output after start-up and an output voltage
that can be programmed by I2C. Each evaluation board is optimized to best perform with the ISL9122A IC series.
The input power and load connections are provided through multi-pin connectors for high-current operations.
The evaluation boards are shown in Figure 4 and Figure 5. Table 1 lists the test points and jumpers for the
boards. The ISL9122A internal registers can be accessed by I2C through the onboard jumper header J5, and its
mode control register configures the part into the various operation modes. See the Evaluation Software
Installation and Use to configure the board output voltage and operation modes.

1.2 Quick Start Guide
For both evaluation boards, the default output voltage is set at 3.3V. Use the following procedures to configure
and power-up the board for proper operation. During the power-on process, the expected waveforms are shown
in Figure 2.
1. Connect the power supply to J1, with voltage setting between 1.8V and 5.5V.
2. Connect the electronic load to J2.
3. Place the scope probes on VOUT test point and other test points of interest.
4. Ensure that the EN pin jumper (J4) is pulled up to VIN.
5. Turn on the power supply. At the end of soft start sequence, ISL9122A is operating in Regulation mode by
default with VOUT = 3.3V.
6. Monitor the output voltage start-up sequence on the scope. The waveforms should look similar to those shown
in Figure 2.
7. Turn on the electronic load.
8. Measure the output voltage with the voltmeter. The voltage should regulate within the datasheet specification
limits.
9. To determine efficiency, measure input and output voltages at the Kelvin sense test points (S+ and S-), which
are part of J1 and J2 headers. The bench power supply can be connected to the VIN and GND headers on J1.
The electronic load can be connected to the VOUT and GND headers on J2. Measure the input and output
currents. Calculate the efficiency based on these measurements.
1.3 Evaluation Software Installation and Use
1. The ISL9122 evaluation software is available for download from the Renesas website. Save the file and install
the evaluation software by double clicking on the file name. Follow the instructions that appear on-screen to
install the application.
2. Attach the USB - I2C interface dongle to the computer using the supplied USB cable.
3. Attach the USB - I2C interface dongle to the 20-pin header J5 on the ISL9122A evaluation board.
4. Following the Quick Start Guide, connect the power supply, DC load, and other test equipment to the evaluation
board; next, apply power.
5. Launch the ISL9122 evaluation software. The installer adds a shortcut in the Start menu
(Start > Intersil > ISL9122 > ISL9122 Evaluation Software Customer).
Select ISL9122 Evaluation Software Customer to launch the evaluation software.
6. When launched, the ISL9122 evaluation software detects the USB - I2C interface, and the CONNECT button
turns green (see Figure 3). If a connection is not established, this button is brown. Select this button once to

force a manual connection; the button should turn green. If the button remains brown, please check the cable
connections, change to another USB port on computer, or try reinstalling the ISL9122 GUI software.
7. Set the 7-bit I2C address to 0x18, which matches with ISL9122A I2C address. Selecting READ ALL reads from
all registers simultaneously and populates all the register panels. Using WRITE ALL overwrites all the writable
registers with the values specified or modified in the GUI.
8. The ISL9122A has five control registers. See Tabl e 2 through Table 6 for detailed register descriptions.
9. Register RO_REG1 (Address: 0x02) provides chip identification information. See Table 2 for its register
contents. The Get IC INFO_RO_REG1 button reads from this read-only register.
10. To change the output voltage, you can use the VSET Control slider in the VSET register (Address: 0x11) panel
and perform a Write REG operation. The output voltage ramps up at the slew rate specified in the DVSRATE
setting of CONV_CFG register. If the modified output voltage is lower than the initial value, its ramp down rate
depends on the applied load and output capacitance. The Read REG button provides the contents of the
register, so adjust the slider accordingly. Use Table 4 to decode the VSET content required for the desired
output voltage.
11. Register INTFLG_REG (Address: 0x03) contains the fault flags. The background color changes from green to
red: when (1) a fault occurs from the list in Table 3, and (2) this register is read using either the Check Fault
button or the READ ALL button. Each bit is set by a fault event and cleared when read. When the bit is cleared
after reading, the background color changes from red back to green.
12. Register CONV_CFG (Address: 0x12) contains crucial converter configuration bits. Table 5 describes its
register contents. Selecting the Write (or Read) button writes (or reads) the entire CONV_CFG register in one
go.
13. Use EN_AND bit to disable the converter through I2C by toggling the Soft Start EN_AND button from
Soft Start enabled to Soft Start inhibit.
14. Selecting the Soft DSCHG enabled button presents a soft discharge resistor on the output pin, when the
converter is disabled through I2C using the EN_AND bit. By default, the Soft DSCHG disabled button is
selected.
15. Use the DVSRATE drop-down list to modify the dynamic voltage scaling rate for voltage ramp up, when output
voltage is modified using the VSET register.
16. Use the FMODE drop-down list to select one of the forced operating modes: Normal (Auto-PFM, default),
Forced PWM and Forced Bypass.
17. Use the CTRL Type drop-down list to select the control mode between Type I and Type II error amplifier.
18. Register INTFLG_MASK (Address: 0x13) contains additional features influencing the part behavior. Selecting
the Write (or Read) button writes (or reads) the entire INTFLG_MASK register in one go.
19. As mentioned in Ta b l e 6 , use OC_FAULT drop-down to select the overcurrent handling mechanism for the
part. By default, the part is set to Hiccup mode during overcurrent, but this setting can be changed to
Shutdown mode or Current Limit mode using this register.
20. Use the EN_OR drop-down list to enable a push-button ON functionality for the EN pin. By default, this feature
is disabled.

2. PCB Layout Guidelines
The ISL9122AIIN-EVZ and ISL9122AIRN-EVZ PCB layouts have been optimized for electrical and thermal
performance.
• The input and output capacitors should be positioned as close to the IC as possible.
• The ground connections of the input and output capacitors should be kept as short as possible, and should be
on the component layer to avoid problems that are caused by high-switching currents flowing through PCB vias.
