LM2853 Datasheet | National Semiconductor

Description The LM2853 synchronous SIMPLE buck regulator is a 550 k Hz 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 100m V increments. Internal type-three pensation enables a low ponent count solution and greatly simplifies external ponent selection. The exposed-pad TSSOP-14 package enhances the thermal performance of the LM2853.
