RT8059
1.
5MHz, 1A, High Efficiency PWM Step-Down DC/DC Converter
General Description
The RT8059 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.
8V to 5.
5V.
The RT8059 is ideally suited for portable electronic devices that are powered by 1-cell Li-ion battery or by 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 applications.
The RT8059 automatically turns off the synchronous rectifier when the i...
