The XL8004 is a monolithic high voltage
switching regulator with PFM that is
specifically designed to operate from a
24V~80V DC supply.
n
Wide 24V to 80V Input Voltage Range
0.2V current sense voltage reference.
Directly drive 3~8 series LED.
Excellent line and load regulation.
High efficiency up to 96%.
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.
Available in TO252-5L package.
The XL8004 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.
