一,产品概述(General Description) The JTM9802 is a monolithic high voltage switching regulator with PFM that is specifically designed to operate from a 12V~80V DC power supply. The JTM9802 is a high efficiency LED driver switching regulator. The LED string is driven at DC constant current rather than constant voltage, thus providing constant light output and enhanced reliability. 二.产品特点(Features) 1.)Operation Voltage DC 12V~80V 2.)0.1V current sense voltage reference. 3.)Directly drive 1~18 Series 1W/3W LED. 4.)Excellent line and load regulation. 5.)Internal Optimize Power HV-MOSFET. 6.)Built in Thermal Shutdown Function. 7.)Built in Current Limiting Function. 8.)Built in Soft-Start Circuit. 9.)Available in TO263-5L package. 10.)Up to 98% efficiency. 三,应用范围 (Applications) LED Lighting & LED LAMP General purpose LED lighting 四.下载产品资料PDF文档
