RT8010GQW - Richtek Function Overview

The RT8010GQW is a high-efficiency pulse-width-modulated (PWM) step-down DC-to-DC Converter for use with MP3 players. Capable of delivering 1A output current over a wide input voltage range from 2.5 to 5.5V, the RT8010/A is ideally suited for portable electronic devices that are powered from 1-cell Li-ion battery or from other power sources such as cellular phones, PDAs and hand-held devices. Two operating modes are available including PWM/low dropout auto-switch and shutdown modes. The internal synchronous rectifier with low RDS(ON) dramatically reduces conduction loss at PWM mode. No external Schottky diode is required in practical application. The RT8010 enters low dropout mode when normal PWM cannot provide regulated output voltage by continuously turning on the upper P-MOSFET. RT8010 enter shut-down mode and consumes less than 0.1µA when EN pin is pulled low. Other features include soft-start and lower internal reference voltage with 2% accuracy.
