XRP6670 Overview
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 frequency is programmable between 300kHz and 2.5MHz via an external resistor.
