1.5MHz, 650mA, High Efficiency Synchronous

PWM Step-Down DC/DC Convert

General Description

The LP3202 is a constant frequency, current mode,

PWM step-down converter. The device integrates a

main switch and a synchronous rectifier for high

efficiency. The 2.1V to 5.5V input voltage range

makes the LP3202 is ideally suited for portable

electronic devices that are powered from 1-cell

Li-ion battery or from other power sources within

the range such as cellular phones, PDAs and

handy-terminals.

Internal synchronous rectifier with low RDS(ON)

dramatically reduces conduction loss at PWM mode.

The

internal

synchronous

switch

increases

efficiency while eliminate the need for an external

Schottky diode.The switching ripple is easily

smoothed-out by small package filtering elements

due to a fixed operation frequency of 1.5MHz. This

along with small SOT-23-5 package provide small

PCB area application. Other features include soft

start, lower internal reference voltage with 2%

accuracy, over temperature protection, and over

current protection.
