Preliminary Data sheet MicroPower Regulated Charge Pump SGM3110 GENERAL DESCRIPTION FEATURES The SGM3110 is a MicroPower switched capacitor voltage converter that delivers a regulated output. No external inductor is required for operation. The SGM3110 can deliver up to 100mA to the voltage regulated output. It features very low quiescent current and high efficiency over a large portion of its load range, making this device ideal for battery-powered applications. Furthermore, the combination of few external components and small package size keeps the total converter board area to a minimum in space-restricted applications. The SGM3110 uses a pulse skipping technique to provide a regulated output from a varying input supply. The SGM3110 contains a thermal management circuit to protect the device under continuous output short-circuit conditions. The SGM3110 has lead (Pb) free SOT23-6 package and is rated over the -40C to +85C temperature range. - Step-Up Voltage Converter - Input Voltage Range: SGM3110-5.0: 2.7 to 5.0V SGM3110-4.5: 2.7 to 4.5V - MicroPower Consumption: 60A - Fixed 5V, 4.5V 4% Output - Peak Current 250mA for 100ms - High Frequency 750kHz Operation - Logic-Controlled Shutdown - Short-Circuit/Over-Temperature Protection - Lead (Pb) Free SOT23-6 Package PIN CONFIGURATIONSTOP VIEW APPLICATIONS Cellular Phones Digital Cameras SGM3110 Handheld Electronics LEDs for Camera Flash Portable Communication Devices MP3 Players GPS Receivers PDAs VOUT 1 GND 2 SHDN 3 3110(A) LED/Display Backlight Driver 6 C+ 5 VIN 4 C- SOT23-6 TYPICAL APPLICATION VOUT COUT = 10F ON/OFF Shengbang Microelectronics Co, Ltd Tel: 86/451/84348461 www.sg-micro.com VOUT C+ GND VIN SHDN C- 1F VIN CIN = 10F Apr. 2007 ELECTRICAL CHARACTERISTICS (TA = -40C to +85C, unless otherwise noted.

Shengbang Micro-electronics recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
