The RT8010C is a high efficiency Pulse-Width-Modulated (PWM) step-down DC-DC converter, and is capable of delivering 1A output current over a wide input voltage range from 2.5V to 5.5V. The RT8010C is ideally suited for portable electronic devices that are powered from 1-cell Li-ion battery or from other power sources such as cellular phones, PDAs and hand-held devices. <p align="justify">Two operating modes are available including : PWM/Low-Dropout autoswitch and shutdown modes. The Internal synchronous rectifier with low R<sub>DS(ON)</sub> dramatically reduces conduction loss at PWM mode. No external Schottky diode is required in practical application. </p><p align="justify">The RT8010C enters Low Dropout mode when normal PWM cannot provide regulated output voltage by continuously turning on the upper P-MOSFET. RT8010C enters shut-down mode and consumes less than 0.1μA when the EN pin is pulled low. </p><p align="justify">The switching ripple is easily smoothed-out by small package filtering elements due to a fixed operating frequency of 1.5MHz. Small WDFN-6L 2x2 package provides small PCB area application. Other features include soft start, lower internal reference voltage with 2% accuracy, over temperature protection, and over current protection.</p>
