Maxim Integrated MAX17681 | Demoboard MAX17681EVKITC

Description

The MAX17681EVKITC 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 the first configuration, the output is programmed to +15V at 200mA, with ±8% output voltage regulation. The second configuration uses a post regulator (MAX17651) to produce +12V at 100mA with less than ±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 Thin-SOT (TSOT) package.
