MAX16932 Evaluation Kit
General Description
Quick Start
The MAX16932 evaluation kit (EV kit) is a fully assembled
and tested application circuit for the MAX16932 high-
voltage, dual synchronous step-down controller. The EV
kit is set up to provide 5V and 3.3V from an input voltage
ranging from 3.5V to 36V. Each buck rail can deliver up
to 5A load current. The EV kit’s switching frequency is set
at 2.2MHz for both buck converters. Various jumpers are
provided to help evaluate features of the MAX16932 IC.

Procedure
The EV kit is fully assembled and tested. Follow the steps
below to activate the board. Caution: Do not turn on the
power supply until all connections are completed.
Benefits and Features
● Dual, Synchronous Step-Down Controllers Operate
at 180° Out-of-Phase to Reduce Switching Noise
1) Verify that all jumpers are in their default configura-
tions according to Table 1.
● 3.5V to 36V Wide Input Supply Range
● Buck Output Voltage: 5V and 3.3V Fixed or
2) Connect the positive and negative terminals of the
power supply to the VBATF and PGND test pads,
respectively.
Adjustable Between 1V and 10V
● Current-Mode Controllers with Forced-PWM and Skip
Modes
3) Connect the positive terminal of the first electronic
load to the VOUT1 test pad. Connect the ground
terminal of the electronic load to the corresponding
PGND test pad.
● Resistor-Programmable Frequency Between 1MHz
and 2.2MHz
● Frequency Synchronization Input
● Independent Enable Inputs
4) Connect the positive terminal of the second electronic
load to the VOUT2 test pad. Connect the ground
terminal of the electronic load to the corresponding
PGND test pad.
● Voltage Monitoring PGOOD_ Outputs
● Fully Assembled and Tested
5) Set the power-supply voltage to 14V.
6) Turn on the power supply.
