80V   1A   Switching   Current   Buck    PFM    LED    Constant  

Current    Driver                                                               XL8004

General Description
 

    The  XL8004  is  a monolithic high voltage switching regulator with

PFM  that  is  specifically  designed  to  operate  from  a  24V~80V DC

supply.
 

    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.

Features
 

   1） Wide 24V to 80V Input Voltage Range
   2） 0.2V current sense voltage reference.
   3） Directly drive 3~8 series LED.
   4） Excellent line and load regulation.
   5） High efficiency up to 96%.
   6） Internal optimize power HV-MOSFET.
   7） Built in thermal shutdown function.
   8） Built in UVLO function.
   9） Built in current limiting function.
 10） Built in LED open & short protection.
 11） Built in soft-start circuit.
 12） Available in TO252-5L package.
 

Applications
 

  1） EBIKE LED Lighting
  2） LED Lighting & LED LAMP
  3） General purpose lighting
