LM2852
2A 500/1500kHz SIMPLE SYNCHRONOUS
Buck
Regulator
General Description
The LM2852 SIMPLE SYNCHRONOUS
buck regulator is
a high frequency step-down switching voltage regulator ca-
pable of driving up to a 2A load with excellent line and load
regulation. The LM2852 can accept an input voltage be-
tween 2.85V and 5.5V and deliver a customizable output
voltage that is factory programmable from 0.8V to 3.3V in
100mV increments. The LM2852 is available with a choice of
two switching frequencies - 500kHz (LM2852Y) or 1.5MHz
(LM2852X). It also features internal compensation to deliver
a
low
component
count
solution.
The
exposed-pad
TSSOP-14 package enhances the thermal performance of
the LM2852.
