UL75 - ADAPTIVE CONDUCTION LINEAR DRIVER

Datasheet Summary

Description

UTC UL75 can drive a plurality of LED strings.

When the voltage detecting circuit detects the different voltage level of input voltage, it can control the LED strings.

If the input voltage is lower that it will bypass some LED strings.

Features

  • Adaptive Conduction.
  • Wide Range, Programmable LED Voltage.
  • Output LED Current available from 50mA to 100mA.
  • Can be Paralleled for Higher Current.
  • 5V to 500V Supply Voltage Range.
  • High Efficiency.
  • Stable LED Brightness.
  • Over Temperature Protection.
  • Patent Pending Drive Architecture.
  • Low THD.

    UNISONIC TECHNOLOGIES CO., LTD UL75 Preliminary ADAPTIVE CONDUCTION LINEAR DRIVER CMOS IC  DESCRIPTION UTC UL75 can drive a plurality of LED strings. When the voltage detecting circuit detects the different voltage level of input voltage, it can control the LED strings. If the input voltage is lower that it will bypass some LED strings. And turn on all LED strings when the input voltage is higher. The number of LEDs in LED array is dependent on the voltage level of the AC power source, That includes of ±10% variations. UTC UL75 is an ideal solution for LED Lamps (e.g. E27, GU10), General Illumination, LED Strings (e.g. T-8 Tube) and Constant Current Sink.  FEATURES * Adaptive Conduction.
