XRP7657 Datasheet 25v Non Synchronous Pwm Step Down Regulator

Manufacturer: Exar (now MaxLinear)

Overview: February 2011 XRP7657 2A, 25V Non Synchronous PWM Step Down Regulator Rev. 2.0.

General Description

The XRP7657 is a non synchronous voltage mode PWM step down (buck) regulator capable of a constant output current up to 2Amps.

A wide 4.75V to 25V input voltage range allows for single supply operations from industry standard 5V, 12V and 24V power rails.

With a 420kHz constant operating frequency and integrated high side switch, the XRP7657 reduces the overall ponent count and solution footprint.
