3 Description

The LM2852 synchronous buck regulator is a high

frequency step-down switching voltage regulator

capable of driving up to a 2A load with excellent line

and load regulation. The LM2852 can accept an input

voltage between 2.85 V and

5.5 V and deliver an output voltage that is factory

programmable from 0.8 V to 3.3 V in 100-mV

increments. The LM2852 is available with a choice of

two switching frequencies –500 kHz (LM2852Y) or

1.5 MHz (LM2852X). It also features internal, typethree

compensation to deliver a low component count

solution. The exposed-pad HTSSOP-14 package

enhances the thermal performance of the LM2852.
