LM2853

3A 550 kHz Synchronous SIMPLE SWITCHER^®Buck

Regulator

General Description

Features

The LM2853 synchronous SIMPLE SWITCHER^®buck regu-

lator 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 compensation enables a low

component count solution and greatly simplifies external

component selection. The exposed-pad TSSOP-14 package

enhances the thermal performance of the LM2853.

n Input voltage range of 3.0V to 5.5V
