Analog Devices MAX17761

Description

The MAX17761 5V output EV kit is a proven design to evaluate the MAX17761 high-efficiency, high-voltage, synchronous step-down DC-DC converter in a TDFN package. The EV kit generates 5V at load currents up to 1A from a 6.5V to 76V input supply. The EV kit features a 400kHz switching frequency for optimum efficiency and component size. The EV kit features adjustable input undervoltage lockout, adjustable soft-start, adjustable switching frequency, adjustable current limit, open-drain RESET signal and external frequency synchronization.
