LM2853 Datasheet Synchronous Simple Switcher Buck Regulator

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: .. LM2853 3A 550 kHz Synchronous SIMPLE SWITCHER ® Buck Regulator October 2006 LM2853 3A 550 kHz Synchronous SIMPLE SWITCHER ® Buck.

General Description

The LM2853 synchronous SIMPLE buck regulator is a 550 kHz step-down switching voltage regulator capable of driving up to a 3A load with excellent line and load regulation.

The LM2853 accepts an input voltage between 3.0V and 5.5V and delivers a customizable output voltage that is factory programmable from 0.8V to 3.3V in 100mV increments.

Internal type-three pensation enables a low ponent count solution and greatly simplifies external ponent selection.
