RT8020E
Dual High-Efficiency PWM Step-Down DC/DC Converter
General Description
The RT8020E is a dual high-efficiency Pulse-WidthModulated (PWM) step-down DC/DC converter.
It is capable of delivering 1A output current over a wide input
voltage range from 2.
5V to 5.
5V.
The RT8020E is ideally suited for portable electronic devices that are powered by 1-cell Li-ion battery or other power sources within the range such as cellular phones, PDAs and other hand-held devices.
Two operational modes are available : PWM/Low-Dropout auto-switch mode and shutdown mode.
Internal synchronous rectifier with low RDS(ON) dramatically reduces conduction loss at PWM mode.
No external Schottky diode is require...
