LP3202 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.
