RT8010/RT8010A

Description


Two operating modes are available including : PWM/Low-Dropout autoswitch and shut-own modes. The Internal synchronous rectifier with low R_DS(ON) dramatically reduces conduction loss at PWM mode. No external Schottky diode is required in practical application.

The RT8010/A enters Low-Dropout mode when normal PWM cannot provide regulated  utput voltage by continuously turning on the upper PMOS. RT8010/A enter shut-down mode and consumes less than 0.1A when EN pin is pulled low.

The switching ripple is easily smoothed-out by small package filtering elements due to a fixed operating frequency of 1.5MHz. This along with small WDFN-6L 2x2 and WQFN-16L 3x3 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.
