Evaluates: MAX16935
MAX16935 Evaluation Kit
General Description
The MAX16935 evaluation kit (EV kit) demonstrates
the MAX16935 high-voltage, current-mode step-down
converter with low operating current. The EV kit operates
over a wide 3.5V to 36V input range and the output is set
for 5V at 3.5A.
The EV kit comes with the MAX16935RAUE/V+ installed.
Features and Benets
● Wide 3.5V to 36V Input Supply Range
● Forced-PWM or Skip-Mode Operation
● Programmable Switching Frequency
● Power-Good Output
● Proven PCB Layout
● Fully Assembled and Tested

Procedure
The EV kit is fully assembled and tested. Follow the steps
below to verify board operation. Caution: Do not turn on
supplies until all connections are made.
1) Verify that jumpers JU1 and JU2 are in their default
positions, as shown in Tables 1 and 2.
2) Connect the power supply between the EXT_VBAT
andnearestPGNDtestpoints.
3) Connect the 3.5A electronic load between the OUT
andnearestPGNDtestpoints.
4) Connect the DVM between the OUT and nearest
PGNDtestpoints.
5) Turn on the power supply.
6) Enable the electronic load.
7) Verify that the voltage at the OUT test point is approxi-
mately 5V.
