Preliminary Datasheet
LP3201
1.
5MHZ,650mA,High Efficiency Synchronous PWM Step-Down DC/DC Convert
General Description
The LP3201 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 LP3201 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...
