Evaluation Kit for the MAX1676

Active: In Production.

The MAX1676 is a high-efficiency, step-up DC-DC converter for portable hand-held devices. It accepts a positive input voltage between 0.7V to 5.5V and converts it to a higher output voltage. The MAX1676 includes a damping circuit (at BATT) that suppresses inductor ringing to reduce electromagnetic interference (EMI).

The MAX1676 evaluation kit (EV kit) is a fully assembled and tested surface-mount printed circuit board. Three jumpers on the EV kit allow for easy access to the output voltage select, current limit, and shutdown features.

The output voltage is both adjustable and pin-selectable. A movable jumper selects either a 3.3V or 5.0V output, or it can be left open and a resistor network can be used to obtain a voltage in the 2V to 5.5V range. The inductor current limit is selectable for either 0.5A or 1.0A. In shutdown mode, the MAX1676 typically draws only 0.1µA.
