The EV kit is fully assembled and tested. Follow the
steps below to verify the board operation. Caution: Do
not turn on power supply until all connections are
completed.
1) Set the power supply at a voltage between 15V and
2) Connect the positive terminal of the power supply
3) Connect the DVM across the VOUT PCB pad and the
4) Turn on the DC power supply.
5) Enable the load.
6) Verify that the DVM displays 12V.
To turn-on /off the part from EN/UVLO, follow the steps
below:
1) Remove resistors R1 and R2.
2) Connect the power supply to the EV kit and turn on

The MAX17502G EV kit provides a proven design to
evaluate the MAX17502G high-efficiency, high-voltage,
synchronous step-down DC-DC converter in a TDFN
package. The EV kit generates 12V at load currents up
to 1A from a 15V to 60V input supply. The EV kit features
a 600kHz fixed switching frequency for optimum effi-
ciency and component size. The EV kit features a forced-
PWM control scheme that provides constant switching-
frequency operation at all load and line conditions.
The EV kit includes an EN/UVLO PCB pad to enable
control of the converter output. An additional RESET
PCB pad is available for monitoring the open-drain logic
output. The VCC PCB pad helps measure the internal
LDO voltage.
The device utilizes an adjustable soft-start function to
limit inrush current during startup. The soft-start time is
adjusted by the value of C3, the external capacitor from
SS to GND. To adjust the soft-start time, determine C3
using the following formula:
