    • Evaluation Kit for the MAX17545 in 3.3V Output-Voltage Application


    The MAX17545 3.3V output evaluation kit (EV kit) provides a proven design to evaluate the MAX17545 high-voltage, high-efficiency, synchronous step-down DC-DC converter.

    The EV kit is preset for 3.3V output at load currents up to 1.7A and features a 450kHz switching frequency for optimum efficiency and component size. The EV kit features adjustable input undervoltage lockout, adjustable soft-start, open-drain active-low RESET signal, and external frequency synchronization.
