MAX17681EVKITB#: ±5 @ 50mA or ±7V @ 100mA, 17 ~ 36V in

Summary

The MAX17681EVKITB 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 configuration one the output is programmed to ±7V @ 100mA, with ±8% output voltage regulation. The second configuration uses a post regulator, MAX17651 to produce ±5V @ 50mA with < ±3% regulation.

The EV kit comes installed with the MAX17681 in a 10-pin(3mm x 2mm) TDFN package and MAX17651 in a 6-lead TSOT package.
