MAX17231EVKIT

Evaluation Kit for the MAX17230/MAX17231


Please check latest availability status for a specific part variant.

Description

The MAX17231 evaluation kit (EV kit) is a fully assembled and tested application circuit board for the MAX17231 high-voltage, dual synchronous step-down controller with preboost. The EV kit is set up to provide 5V and 3.3V from an input voltage ranging from 3.5V to 36V. The preboost circuit maintains the 10V supply rail for input voltages below 10V. Each buck rail can deliver up to 5A load current. Various jumpers are provided to help evaluate features of the MAX17231 IC.
