Beschreibung

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.
