Product Details

The MAX17521EVKITE# evaluation kit (EV kit) provides a proven design to evaluate the MAX17521 high-efficiency, high-voltage, Himalaya synchronous step-down dual DC-DC converter. The EV kit is preset to generate 5V and 3.3V output voltages, at load currents up to 1A per converter. The switching frequency of the EV kit is preset to 560kHz for optimum efficiency and component size. The EV kit features programmable enable and input undervoltage lockout (EN/UVLO), programmable soft-start (SS), open-drain status (active-low RESET) output and external clock synchronization (SYNC). The EV kit also provides good layout example, which is optimized for conducted, radiated EMI, and thermal performance. For more details about the IC Benefits and Features, refer to the MAX17521 IC data sheet.
