Product Details

The MAX17681E evaluation kit (EV kit) is a fully assembled and tested circuit board that demonstrates the performance of the MAX17681A 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 output is programmed to ±15V, 75mA each and ±7.5V, 75mA each with ±10% regulation.

The EV kit comes installed with the MAX17681A in a 10-pin (3mm x 2mm) TDFN package.
