JIANGSU CHANGJING ELECTRONICS TECHNOLOGY CO., LTD Low Quiescent Current, PFM/PWM Synchronous Boost Converter CJ9112T6  INTRODUCTION:  FEATURES: The CJ9112T6 is a compact, high-efficiency, fixed frequency, synchronous step-up DCDC converter.This device provides an easyto-use power supply solution for applications powered by either one-cell, two-cell or three-cell alkaline, NiCd, NiMH, one-cell LiIon or Li-Polymer batteries. A low-voltage technology allows the regulator to start up without high inrush current or output voltage overshoot from a low voltage input. High efficiency is accomplished by integrating the low-resistance N-Channel boost switch and P-Channel switch. All synchronous compensation and protection circuitry are integrated to minimize external components. CJ9112T6 consumes less than 14 µA from battery, while operating at no load (VOUT = 3.3V, VIN = 1.5V). The devices provide a true disconnect from input to output (CJ9112T6A) or an input-to-output bypass (CJ9112T6B), while in shutdown (EN = GND) state. Both options consume less than 0.6 µA from battery. Output voltage is set by a small external resistor divider.   Up to 96% Typical Efficiency 1.0A Typical Peak Input Current Limit: IOUT > 200mA@VOUT=3.3V, VIN=1.2V  IOUT > 400mA@VOUT=3.3V, VIN=2.4V  IOUT > 400mA@VOUT=5.0V, VIN=3.3V Low Device Quiescent Current: -Output Quiescent Current: < 4 µA typical, device is not switching (VOUT > VIN, excluding feedback divider current) -Input Sleep Current: 1 µA -No Load Input Current: 14 µA typical  Shutdown Current: 0.6 µA typical   Low Start-up Voltage: 0.82V, 1 mA load Low Operating Input Voltage: down to 0.65V  Adjustable Output Voltage Range: 1.8V to 5.5V  Maximum Input Voltage:  Automatic PFM/PWM Operation: VOUT < 5.5V -PWM Operation: 500 KHz -PFM Output Ripple: 150 mV typical  Feedback voltage: 1.215V  Inrush Current Limiting and Internal Soft Start (1 ms typical)  Selectable, Logic Controlled, Shutdown States: -True Load Disconnect Option (CJ9112T6A) -Input to Output Bypass Option (CJ9112T6B)  Over temperature Protection  Output Short Protection  APPLICATIONS：  One, Two and Three Cell Alkaline and NiMH/NiCd   Solar Cell Applications Personal Care and Medical Products  Bias for Status LEDs  Smartphones, MP3 Players, Digital Cameras PIN CONFIGURATION Portable Products  DEVICE INFORMATION: PART NUMBER CJ9112T6 www.jscj-elec.com PACKAGE SOT-23-6L  Remote controllers, Portable Instruments  Wireless Sensors  Bluetooth Headsets  +3.3V to +5.0V Distributed Power Supply 1 Rev. - 1.0 PDF
