XRP6670 Datasheet (Exar) - 3A 300kHz-2.5MHz Synchronous Step Down Regulator

XRP6670, 3A 300kHz-2.5MHz Synchronous Step Down Regulator

The XRP6670 is a synchronous current mode PWM step-down (buck) regulator capable of delivering up to 3 Amps.

A 2.6V to 5.5V input voltage range allows for single supply operation from industry standard 3.3V and 5V power rails.

Based on a current mode PWM control scheme, the XRP6670 operating frequen
