MAX17681EVKITC#: 15V @ 200mA or 12V @ 100mA, 17 ~ 36V in

Summary

The MAX17681EVKITC is a fully assembled and tested circuit board that demonstrates the performance of the MAX17681 high-efficiency, iso-buck DC-DC converter. The EV kit operates over a wide input-voltage range of 17V to 36V and uses primary-side feedback to regulate the output voltage.

The EV kit has two output configurations. In the first configuration, the output is programmed to +15V at 200mA, with ±8% output voltage regulation. The second configuration uses a post regulator (MAX17651) to produce +12V at 100mA with better than ±3% regulation.
