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/Low-
Dropout autoswitch and shut-down modes, the Internal

Pin Configurations
Marking Information
synchronous rectifier with low R
DS(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 shut-
down 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 Prototype area application. Other
features include soft start, lower internal reference voltage
with 2% accuracy, over temperature protection, and over
current protection.
