1.5MHZ,600mA,High Efficiency Synchronous

PWM Step-Down DC/DC Convert

General Description

The LP3203 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 LP3203 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

TSOT-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。
