Quick Start
Recommended Equipment
● MAX17502F EV kit
● 7V to 60V, 2A DC input power supply
● Load capable of sinking 1A
● Digital voltmeter (DVM)
● Function generator
Procedure
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 7V and
2) Connect the positive terminal of the power supply to
3) Connect the DVM across the VOUT PCB pad and the
4) Verify that a shunt is installed across pins 1-2 on
5) Turn on the DC power supply.
6) Enable the load.
7) Verify that the DVM displays the expected voltage.
To turn-on/off the part from EN/UVLO, follow the steps
below:
1) Remove resistors R1 and R2 and the jumper installed
2) Connect the power supply to the EV kit and turn on

Detailed Description of Hardware
The MAX17502F EV kit provides a proven design to
evaluate the MAX17502F high-efficiency, high-voltage,
synchronous step-down DC-DC converter. The EV kit
generates a fixed 5V, at load currents up to 1A, from a
7V to 60V input supply. The EV kit features a 600kHz
fixed switching frequency for optimum efficiency and
component size. The EV kit features a forced-PWM con-
trol scheme that provides constant switching-frequency
operation at all load and line conditions.
The EV kit includes an EN/UVLO PCB pad and jumper
JU1 to enable control of the converter output. An addi-
tional RESET PCB pad is available for monitoring the
converter output. The VCC PCB pad helps measure the
internal LDO voltage.
Soft-Start Input (SS)
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:
