80V  1A  High  Efficiency  Buck  PFM  LED  Constant Current

Driver                                                                              XL8002

General Description

    The XL8002 is a monolithic high voltage switching regulator with PFM that

is specifically designed to operate from a 12V~80V DC power supply.

    The  XL8002  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 1~18 Series 1W/3W 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 TO263-5L package.
10)  Up to 98% efficiency.

Applications

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