Overview
® RT8016 1.
5MHz, 1A, High Efficiency PWM Step-Down DC/DC Converter General Description The RT8016 is a high-efficiency Pulse-Width-Modulated (PWM) step-down DC-DC converter.
Capable of delivering 1A output current over a wide input voltage range from 2.
5V to 5.
5V, the RT8016 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.
Two operating modes are available including : PWM/LowDropout autoswitch and shut-down modes, the Internal synchronous rectifier with low RDS(ON) dramatically reduces conduction loss at PWM mode.
No external Schottky diode is required in practical application.
The RT8016 enters Low-Dropout mode when normal PWM cannot provide regulated output voltage by continuously turning on the upper PMOS.
The RT8016 enters shutdown mode and consumes less than 0.
1uA when EN pin is pulled low.
The RT8016 also offers a range of 1V to 3.
3V with 0.
1V per step or adjustable output voltage by two external resistor.
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 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.
