General Description

The MAX25255 dual phase evaluation kit (EV kit) provides

a proven design to evaluate the MAX25254/

MAX25255 automotive 2MHz synchronous buck converter

dual phase operation. The EV kit comes with a

MAX25255DAFDA/VY+ (3.3V/2MHz) installed, as well as

various test points and jumpers for evaluation.

The EV kit is designed to deliver up to 12A with input voltage

3V to 36V. The output voltage quality can be monitored

by observing the PGOOD1 signal. The EV kit can

also be used to evaluate other MAX25254/MAX25255

variants with minimal component changes.
