™

2A 500/1500kHz SIMPLE SYNCHRONOUS Buck

Regulator

General Description

Features

n Input voltage range of 2.85 to 5.5V

n Factory EEPROM set output voltages from 0.8V to 3.3V

in 100mV increments

™

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

n Maximum Load Current of 2A

n Voltage Mode Control

n Internal type three compensation

n Switching frequency of 500kHz or 1.5MHz

n Low standby current of 10µA

n Internal 60 mΩ MOSFET switches

n Standard voltage options 1.0/1.2/1.5/1.8/2.5/3.3 volts

low component count solution. The exposed-pad

TSSOP-14 package enhances the thermal performance of

the LM2852.

Applications

n Low voltage point of load regulators

n Local solution for FPGA/DSP/ASIC core power

n Broadband networking and communications

infrastructure

n Portable computing
