3 Description

The LM2853 synchronous 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 V and 5.5 V and delivers a customizable

output voltage that is factory programmable from 0.8

V to 3.3 V in 100 mV increments. Internal type-three

compensation enables a low component count

solution and greatly simplifies external component

selection. The HTSSOP-14 (PWP) package

enhances the thermal performance of the LM2853.
