1 / 15 page  RT8010/A 1 DS8010/A-02 March 2007 www.richtek.com Features +2.5V to +5.5V Input Range Output Voltage (Adjustable Output From 0.6V to VIN) RT8010 : 1.0V, 1.2V, 1.5V, 1.6V, 1.8V, 2.5V and 3.3V Fixed/Adjustable Output Voltage RT8010A Adjustable Output Voltage Only 1A Output Current 95% Efficiency No Schottky Diode Required 1.5MHz Fixed-Frequency PWM Operation Small 6-Lead WDFN and 16-Lead WQFN Package RoHS Compliant and 100% Lead (Pb)-Free Applications Mobile Phones Personal Information Appliances Wireless and DSL Modems MP3 Players Portable Instruments 1.5MHz, 1A, High Efficiency PWM Step-Down DC/DC Converter General Description The RT8010/A 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 RT8010/A 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 synchronous rectifier with low RDS(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 output voltage by continuously turning on the upper PMOS. RT8010/A enter shut-down mode and consumes less than 0.1 μA 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. Note : RichTek Pb-free and Green products are : RoHS compliant and compatible with the current require- ments of IPC/JEDEC J-STD-020. Suitable for use in SnPb or Pb-free soldering processes. 100% matte tin (Sn) plating.
