Evaluation Kit MAX17681A for Isolated ±15V or ±12V Output Configuration

Please check latest availability status for a specific part variant.


The MAX17681A evaluation kit (EV kit) is a fully assembled and tested circuit board that demonstrates the performance of the MAX17681A high-efficiency, isobuck 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 less than ±3% regulation.

The EV kit comes installed with the MAX17681A in a 10-pin (3mm × 2mm) TDFN package and MAX17651 in a 6-pin TSOT package.
