Overview
RT8009 1.
25MHz, 600mA, High Efficiency PWM Step-Down DC/DC Converter General Description The RT8009 is a high-efficiency pulse-width-modulated (PWM) step-down DC-DC converter.
Capable of delivering 600mA output current over a wide input voltage range from 2.
5 to 5.
5V, the RT8009 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 com as cellular phones, PDAs and handy-terminals.
Internal synchronous rectifier with low RDS(ON) dramatically reduces conduction loss at PWM mode.
No external Schottky diode is required in practical application.
The RT8009 automatically turns off the synchron...
