Offline Controller for LED Lighting with Power Factor Correction


TopologyFlyback Converter
Input voltage85-270 V
Output 1110 V / 0.16 A
IC revision1


The XC9404 series are LED lighting offline controllers that use PFM(Pulse Frequency Modulation) control and have a Power Factor improvement function. The operating input voltage range is 85VAC to 270VAC, and the current is controlled on the primary side without using a Opto-coupler or secondary side control circuit. Because LED current fluctuations caused by input voltage fluctuations and LED voltage fluctuations can be suppressed, a stable LED lighting power supply is obtained.


  • Operating Voltage: 85VAC ~ 270VAC
  • Output Wattage: up to 50W
  • Power Factor / THD: Power Factor 0.95 or more / THD up to 10% attainable
  • Harmonics regulations: IEC61000-3-2 class C compliance possible
  • Control Method: PFM Control
  • Function: Opto-coupler free due to primary control, Built-in acceleration Start, Low Start up Current 20μA
  • Protection Function: LED Open/Short protection, Over Voltage Protection, Over Current Protection, UVLO
  • Package: SOP-8D
  • Operation Ambient Temperature: 40℃ ~ +105℃

Typical applications

  • LED Lighting
