RT8010/A
1.
5MHz, 1A, High Efficiency PWM Step-Down DC-DC Converter
General Description
The RT8010/A is a high efficiency Pulse-Width-Modulated (PWM) step-down DC-DC converter.
Capable of delivering 1A output current over a wide input
voltage range from 2.
5V 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/LowDropout autoswitch 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 pract...
