MAX17574EVKITA#: 3.3V @ 3A, 5 ~ 60V in, Buck

Summary

The MAX17574 3.3V output 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 3.3V output from 5V to 60V input at load currents up to 3A and features a 500kHz switching frequency for optimum efficiency and component size.

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.
