RT8025 Overview
Key Features
- The RT8025 is a high-efficiency pulse-width-modulated (PWM) step-down DC/DC converter
- Internal synchronous rectifier with low RDS(ON) dramatically reduces conduction loss at PWM mode
- No external Schottky diode is required in practical application
- The RT8025 automatically turns off the synchronous rectifier while the inductor current is low and enters discontinuous PWM mode
- This can increase efficiency at light load condition
- The RT8025 enters Low-Dropout mode when normal PWM cannot provide regulated output voltage by continuously turning on the upper P-MOSFET
- RT8025 enter shutdown mode and consumes less than 0.1μA when EN pin is pulled low
- The switching ripple is easily smoothed-out by small package filtering elements due to a fixed operation frequency of 1.25MHz
- This along with small SOT-23-5 and TSOT-23-5 package provides small PCB area application
