Product Details

The MAX17686EVKITA# is a fully assembled and tested circuit board that demonstrates the performance of the MAX17686 high-efficiency, iso-buck DC-DC Converter. The EV kit operates over a wide input-voltage range of 17V to 60V and uses primary-side feedback to regulate the output voltage. The EV kit output is programmed to +24V at 100mA, with ±8% output voltage regulation.

The EV kit comes installed with the MAX17686 in a 10-pin (3mm x 2mm) TDFN package.
