RT8092

The RT8092 is a Peak-Current Mode Pulse-Width- Modulated (PWM) step-down DC/DC converter with I2C control interface. Capable of delivering 4A continuing output current over a wide input voltage range from 2.5V to 5.5V, the RT8092 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 barrier diode is required in practical application. The RT8092 enters low-dropout mode when normal PWM cannot provide regulated output voltage by continuously turning on the upper P-MOSFET. The RT8092 enters shutdown mode and consumes less than 5μA when the EN pin is pulled low. The switching ripple is easily smoothedout by small package filtering elements due to a fixed operation frequency of 3MHz. This along with small WL-CSP-15B 1.2x2 (BSC) and WQFN-14L 3.5x3.5 packages provides small PCB area applications.资料下载
