JIANGSU CHANGJING ELECTRONICS TECHNOLOGY CO., LTD 1.1A 1.2MHz Synchronous Boost Converter CJ9311 Series „ INTRODUCTION: „ FEATURES: The CJ9311 devices provide a power supply solution for products powered by either a one-cell, two-cell, or three-cell alkaline, NiCd or NiMH, or one-cell Li-ion or Li-polymer battery. The boost converter is based on a fixed frequency, pulse-width-modulation (PWM) controller using a synchronous rectifier to obtain maximum efficiency, which contains an internal NMOS switch and PMOS synchronous rectifier. The maximum peak current in the boost switch is typically limited to a value of 1.1A. A switching frequency of 1.2MHz minimizes solution footprint by allowing the use of tiny, low profile inductors and ceramic capacitors. The current mode PWM design is internally compensated, reducing external parts count. Anti-ringing control circuitry reduces EMI concerns by damping the inductor in discontinuous mode. In shutdown, VOUT and VIN are connected, which allows the input battery to be used for backup power. The device features low shutdown current less than 1μA. z z z z z z z z z z Up to 96% Efficiency Delivers 100mA@3.3V from Single AA Cell Delivers 300mA@5V from Two AA Cells Delivers 600mA@5V from Single Li Cell Maintains High Efficiency Over the Output Current Range for Improved Battery Life Low Voltage Start-Up: 0.85V Continuous Switching at Light Loads Internal Synchronous Rectifier Current Mode Control with Internal Compensation 1.2MHz Fixed Frequency Switching Input Range: 0.9V to5V Output Range: 2.5V to 4.5V (Up to 5V with Schottky) Logic Controlled Shutdown(<1μA) Anti-ringing Control Minimizes EMI 1.1A Peak Switch Current Limit Over Temperature Protection Tiny External Components z z z z GPS Receivers LCD Bias Supplies Handheld Instruments Portable Audio Players „ DEVICE INFORMATION: „ APPLICATIONS： z z z z Digital Still and Video Cameras Personal Information Appliances Wireless and DSL Modems Personal Medical Products „ PIN CONFIGURATION www.jscj-elec.com z z z z z z z 1 PART NUMBER PACKAGE CJ9311T6 SOT-23-6L Rev. - 1.0 PDF
