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:
