FEATURES
DESCRIPTION
The LM2852 SIMPLE SWITCHER® synchronous
2
•
Input Voltage Range of 2.85 to 5.5V
buck regulator is
a high frequency step-down
•
Factory EEPROM Set Output Voltages from
0.8V to 3.3V in 100mV Increments
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 2.85V
and 5.5V and deliver an 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, type-
three compensation to deliver a low component count
solution. The exposed-pad HTSSOP-14 package
enhances the thermal performance of the LM2852.
