Product Details

The MAX17557EVKITE# evaluation kit (EV kit) provides a proven design to evaluate the MAX17557 high-efficiency, high-voltage, Himalaya synchronous step-down DC-DC controller. The EV kit is preset to generate 5V output at load currents up to 10A from a 6.5V to 48V input supply. The EV kit features a 350kHz switching frequency for optimum efficiency and component size. The EV kit features PCB pads for enable/disable functionality, opendrain power-good (PGOOD) output, and external clock synchronization (MODE/SYNC). The EV kit also provides a good layout example, which is optimized for conducted, radiated EMI, and thermal performance. For more details about the device, refer to the MAX17557 IC data sheet’s Benefits and Features section.
