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.
