RT8009
RT8009 is manufactured by Richtek.
1.25MHz, 600mA, High Efficiency PWM Step-Down
DC/DC Converter
General Description
Features
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 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 synchronous...
