1 / 9 page UNISONIC TECHNOLOGIES CO., LTD UC3380 CMOS IC www.unisonic.com.tw 1 of 9 Copyright © 2010 Unisonic Technologies Co., Ltd QW-R502-099.C PWM STEP UP DC-DC CONTROLLER DESCRIPTION The UC3380 is PWM step up DC-DC switching controller that operates from 0.9V. The low start up input voltage makes UC3380 specially designed for powering portable equipment from one or two cells battery packs. This device consist of a soft start circuit, a reference voltage source, an error amplifier, an oscillator, a phase compensation, a PWM controller and an output drive circuit for driving external power transistor. Additionally, a chip enable feature is provided to power down the converter for extended battery life. The device features a voltage mode PWM control loop, providing stable and high efficiency operation over a broad load current range. FEATURES * 0.9V Low Start-Up Input Voltage at 1mA Load * Low Operation Current * 0.5uA Low Shutdown Current * Fix Frequency PWM at 100KHZ * Built in PWM Switching Control Circuit ,Duty Ratio is 0~83% * Output Voltage:0.1V Step Setting is Available Between 2.0V and 6.5V * Soft Start Time: 6ms * Shutdown Function APPLICATIONS *Portable Devices *Electronic Games *Portable Audio (MP3) *Personal Digital Assistant (PDA) *Digital still Cameras(DSC) *Camcorders *White LED Driver *Single and Dual-Cell Battery Operated Products ORDERING INFORMATION Ordering Number Lead Free Halogen Free Package Packing UC3380L-xx-AF5-R UC3380G-xx-AF5-R SOT-25 Tape Reel |
