MAX8649EVKIT

Evaluation Kit for the MAX8649


Please check latest availability status for a specific part variant.

Description

The MAX8649 evaluation kit (EV kit) is a fully assembled and tested circuit for evaluating the MAX8649 1.8A step-down regulator. The EV kit operates from a 2.5V to 5.5V supply voltage and outputs a voltage programmable from 0.75V to 1.38V at up to 1.8A. An on-board USB-to-I²C interface and EV kit software control the output voltage, operating modes, and other features of the IC.
