80V  0.5A  High  Efficiency Buck PFM LED Constant Current

Driver                                                                              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.

Features

  1） Operation Voltage DC 12V~80V.
  2） 0.1V current sense voltage reference.
  3） Directly drive 1~8 Series 1W LED.
  4） Excellent line and load regulation.
  5） Internal Optimize Power HV-MOSFET.
  6） Built in Thermal Shutdown Function.
  7） Built in Current Limiting Function.
  8） Built in Soft-Start Circuit.
  9） Available in SOIC-8 package.
10） Up to 97% efficiency.

Applications

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