Product Details

The MAX863 evaluation kit (EV kit) is an assembled and tested PC board that demonstrates the MAX863 dual, step-up DC-DC controller. The EV kit is factory preset to provide 5V and 3.3V outputs at 700mA and 1.1A, respectively (VIN = 2.4V). Both outputs can also be set to other voltages by pin-strapping or with external resistors.

Applications
