LM2852
SNVS325E – JANUARY 2005 – REVISED JANUARY 2016
LM2852 2A 500/1500 kHz Synchronous Buck Regulator
1 Features
1
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, type-
three compensation to deliver a low component count
solution. The exposed-pad HTSSOP-14 package
enhances the thermal performance of the LM2852.
