General Description

The LM2852 SIMPLE SWITCHER

廬

synchronous buck regu-

lator is a high frequency step-down switching voltage regu-

lator 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 incre-

ments. The LM2852 is available with a choice of two switch-

ing frequencies - 500kHz (LM2852Y) or 1.5MHz (LM2852X).

It also features internal, type-three compensation to deliver a

low component count solution. The exposed-pad TSSOP-14

package enhances the thermal performance of the LM2852.

Features

Input voltage range of 2.85 to 5.5V

Factory EEPROM set output voltages from 0.8V to 3.3V

in 100mV increments

Maximum load current of 2A

Voltage Mode Control

Internal type-three compensation

Switching frequency of 500kHz or 1.5MHz

Low standby current of 10碌A(chǔ)

Internal 60 m鈩?MOSFET switches

Standard voltage options 0.8/1.0/1.2/1.5/1.8/2.5/3.3 volts

Applications

Low voltage point of load regulation

Local solution for FPGA/DSP/ASIC core power

Broadband networking and communications

infrastructure

Portable computing
