MAX17504EVKITB#: 5V @ 3.5A, 7.5 ~ 60V in, Buck

Summary

The MAX17504 5V output evaluation kit (EV kit) provides a proven design to evaluate the MAX17504 high-voltage, high-efficiency, synchronous step-down DC-DC converter.

The EV kit is preset for 5V output at load currents up to 3.5A and features a 500 kHz 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 of operation based on light-load performance requirements. An additional RESET PCB pad is available for monitoring whether the converter output is in regulation.
