The MAX1572 evaluation kit (EV kit) is a fully assembled

and tested circuit board that evaluates the MAX1572

PWM step-down DC-DC converter. The circuit operates

from 2.6V to 5.5V and has a fixed 1.5V output capable

of delivering 800mA. It also provides a RESET output.

The EV kit can be used to evaluate other output voltage

versions of the MAX1572 by replacing the IC.
