Preliminary Datasheet
XL8001
General Description
The XL8001 is a monolithic high voltage switching regulator with PFM that is specifically designed to operate from a 12V~80V DC power supply. The XL8001 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.
Operation Voltage DC 12V~80V. 0.1V current sense voltage reference. Directly drive 1~8 Series 1W LED. Excellent line and load regulation. Internal Optimize Power HV-MOSFET. Built in Thermal Shutdown Function. Built in Current Limiting Function. Built in Soft-Start Circuit. Available in SOIC-8 package.
