Product Details

The MAX17681 evaluation kit (EV kit) 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 32V 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 100mA, with ±10% output-voltage regulation. The second configuration uses a post regulator (MAX17651) to produce ±12V at 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-pin TSOT package.
