The MAX17761EVKITB# from Maxim Integrated Products is an evaluation kit (EV kit) for 5V output MAX17761. It 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 and open-drain active-low RESET signal. Typical application includes base station power supplies, distributed supply regulation, general-purpose point-of-load, high-voltage, single-board systems, industrial control power supplies and wall transformer regulation.
