General Description

The RT8025 is a high-efficiency pulse-width-modulated (PWM) step-down DC/DC converter. Capable of delivering 400mA output current over a wide input voltage range from 2.5 to 5.5V, the RT8025 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.
