MAX17574EVKITB#: 5V @ 3A, 6.5 ~ 60 Vin, Buck

Summary

The MAX17574 5V output evaluation kit (EV kit) provides a proven design to evaluate the MAX17574 high-voltage, high-efficiency, synchronous step-down DC-DC converter. The EV kit is preset for 5V output at load currents up to 3A and features a 500kHz switching frequency for optimum efficiency and component size. The EV kit features adjustable input undervoltage lockout, adjustable soft-start, open-drain RESET signal, and external frequency synchronization.

The EV kit includes an EN/UVLO PCB pad and jumper JU1 to enable the output at a desired input voltage.

The SYNC PCB pad and jumper JU3 allow an external clock to synchronize the device. Jumper JU2 allows the selection of a particular MODE/SYNC of operation based on light-load performance requirements. An additional RESET PCB pad is available for monitoring whether the converter output is in regulation.
