XLSEMI 600V 0.5A Switching Current Buck PFM LED Constant Current Driver Features n n n n n n n n n n n n n Datasheet XL5006 General Description The XL5006 is a monolithic high voltage switching regulator with PFM that is specifically designed to operate from a rectified 85V~265V AC mains supply. The XL5006 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. Operate from a rectified 85V~265V AC mains supply. 0.1V current sense voltage reference. Directly drive 1~5 series 1W LED. Excellent line and load regulation. Internal optimize power HV-MOSFET. Built in thermal shutdown function. Built in UVLO function. Built in current limiting function. Built in LED open & short protection. Built in soft-start circuit. Support without electrolytic capacitor System solution. Available in SOIC-8 package. PF > 0.9 (Power Factor) with suitable External components.
