Datasheet Summary
3A 300kHz-2.5MHz Synchronous Step Down Regulator
November 2019
GENERAL DESCRIPTION
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. This flexibility allows the XRP6670 to optimize ponent selection and reduce ponent count and solution footprint. It provides a low output voltage ripple, excellent line and load regulation and has a 100% duty cycle LDO mode....
