一,产品概述(General Description) The JTM9805 is a monolithic high voltage switching regulator with PFM that is specifically designed to operate from a 24V~100V DC supply. The JTM9805 is a high efficiency LED driver switching regulator. The LED string is driven at DC constant current rather than constant voltage, thus providing constant current output and enhanced reliability 二.产品特点(Features) 1.)Wide 24V to 100V Input Voltage Range 2.)0.2V current sense voltage reference. 3.)Directly drive 3~8 series 1W LED. 4.)Excellent line and load regulation. 5.)High efficiency up to 96%. 6.)Minimum Drop out >6V. 7.)Internal optimize power HV-MOSFET. 8.)Built in thermal shutdown function. 9.)Built in UVLO function. 10.)Built in current limiting function. 11.)Built in LED open & short protection. 12.)Built in soft-start circuit. 13.)Available in SOIC-8 package. 三,应用范围 (Applications) EBIKE LED Lighting LED Lighting & LED LAMP General purpose lighting 四.下载产品资料PDF文档
