Product Details

The MAX17687EVKITA# evaluation kit (EV kit) is a fully assembled and tested circuit board that demonstrates the performance of the MAX17687 high-efficiency, iso-buck DC-DC Converter. The EV kit operates over a wide inputvoltage range of 16V to 60V and uses primary-side feedback to regulate the output voltage. The EV kit has isolated output, programmed to +12V at 750mA, with 10% output voltage regulation.

The EV kit comes installed with the MAX17687 in a 20-pin (4mm x 4mm) TQFN package.
