Technical content
PM2402 is dimmable BUCK constant current driver with f ixed Toff . Multiple patented technologies make it possible to achieve high-precision constant current accuracy with very few external components .PM2402 is mainly used in constant current drive power supply system with power less than 500W. The input voltage of PM2402 is very wide, reaching from DC12V to 500V.It can be used in either DC/DC system or AC/DC system. By setting the external capacitance value of the PIN TS, the system can work in DCM, BCM or all CCM respectively. PM2402 integrates patented dimming technology and can be directly compatible with PWM or analog dimming signals. PM2402 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. PM2402 is packaged in ESOP8. FEATURE Ultra-wide working voltage 12V~500V Can work in DCM,BCM or CCM High voltage start-up and power supply PWM/Analogy dimmable Closed-loop constant current control technology 3%Constant current accuracy Single winding inductor High-precision 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
