BOOST High PF Low THD CC Driver ESCRIPTION PM2300 is a Boost constant current control chip of QR Mode . Multiple patented technologies make it possible to achieve high PF and low THD with very few external components.PM2300 is mainly used in constant current drive power suppl y system with power less than 80W.PM2300 is a QR Mode Boost constant current control chip. PM2300 can achieve high precision output constant current under wide input, output voltage and peripheral inductance parameters. Combine QR mode and MOSFET drain Voltage Valley -bottom opening technology to achieve high efficiency and low electromagnetic interference. PM2300 also integrates patented inductance current cancellation technology, which greatly red uces the volume and cost of the main inductor. PM2300 integrates multiple protection functions, such as output open circuit, over-temperature protection, open circuit and short circuit protection of all pins to make sure LED driver more reliable. PM2300 is packaged in SOP8. FEATURE High PF or low THD Ultra-wide working voltage High voltage start-up and power supply Inductive peak current elimination technology QR and MOSFET driver technology Closed-loop constant current control technology Single winding inductor Programmable output open-circuit protection CS resistance short circuit protection Over temperature compensation

These are stress ratings only and functional operation of the device at these or any other condition beyond those indicated in the Electrical Characteristics section of the specification is not implied. The “Electrical Characteristics” table defines the conditions for actual device operation. Exposure to absolute maximum rated conditions for extended periods may affect device reliability. For the parameter without Max./Min. limit, the typical value defines the operation range, the accuracy is not guaranteed by the specification. (2) All voltages are with respect to GND, unless otherwise specified. www.shunyegroup.com.cn
