1 / 13 page RT8016L 1 DS8016L-02 March 2011 www.richtek.com Features Input Range : 2.5V to 5.5V Adjustable Output Voltage Range : 0.6V to VIN 600mA Output Current Efficiency up to 95% No Schottky Diode Required 1.5MHz Fixed-Frequency PWM Operation RoHS Compliant and Haloger Free Applications Mobile Phones Personal Information Appliances Wireless and DSL Modems MP3 Players Portable Instruments 1.5MHz, 600mA, High Efficiency PWM Step-Down DC/DC Converter General Description The RT8016L is a high-efficiency Pulse-Width-Modulated (PWM) step-down DC/DC converter capable of delivering up to 600mA output current over a wide input voltage range from 2.5V to 5.5V. The RT8016L 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 mode and shut-down mode. 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 RT8016L enters low dropout mode when normal PWM can not provide regulated output voltage by continuously turning on the upper P-MOSFET. The RT8016L enters Shut-down mode and consumes less than 0.1 μA when the EN pin is pulled low. The RT8016L also offers a fixed output voltage with a range from 1V to 3.3V with 0.1V per step or an adjustable output voltage via two external resistors. The switching ripple is easily smoothed out by small package filtering elements due to a fixed operating frequency of 1.5MHz. Other features include soft-start, lower internal reference voltage with 2% accuracy, over temperature protection, and over current protection. The IC is available in a WQFN-8L 1.6x1.6 (COL) package which allows small PCB area application.
