LM2853
3A 550 kHz Synchronous SIMPLE SWITCHER® Buck
Regulator
General Description
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.
