The MAX767 evaluation kit (EV kit) is a fully assembled and tested printed circuit board for Maxim's synchronous, step-down power-supply controller. Providing a tightly regulated 3.3V output voltage from a 5V input source, the EV kit contains two separate, complete circuits with conversion efficiencies greater than 90%. The first all-surface-mount circuit can drive loads up to 1.5A, and the second circuit can drive loads up to 5A.
