Evaluation Kit for the MAX1772

Please check latest availability status for a specific part variant.


The MAX1772 evaluation kit (EV kit) is an accurate and efficient multichemistry battery charger. It uses analog inputs to control charge voltage and current. The EV kit can charge any battery with charge current up to 4A. High efficiency is achieved by a buck topology with synchronous rectification. The EV kit provides outputs that can be used to monitor the input current, battery charging current, and the presence of an AC adapter.

The MAX1772 EV kit is a fully assembled and tested surface-mount printed circuit (PC) board.
