General Description of XL8005
The XL8005 is a monolithic high voltage switching regulator with PFM that is specifically designed to operate from a 24V~100V DC supply.
The XL8005 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.
The XL8005 is a switch buck boost DC-DC converter chip; chip integrated 120V high voltage MOSFET, less periphery components required. The chip has a Line regulation and load regulation rate of color. The chip integrated over-current protection,over temperature protection, short circuit protection and reliability of the module.
The XL8005 for the SOP-8L package, using standard external components, flexible application.
