The AL8823 is a boost controller that delivers an accurate constant current for MR16, AR111 and similar LED Lamps. With proprietary control scheme, the LED driver is compatible with many commonly used electronic transformers and provides designs with High Power Factor (PF) and low Total Harmonic Distortion (THD) for these applications. The operation frequency is up to 1MHz that allows the use of small size inductor. With external MOS, the AL8823 can be used for wide range of output powers. 


  • Wide Input Voltage Range: 5V to 36V
  • Continuous Conduction Mode (CCM) Operation
  • Up to 1MHz Switching Frequency
  • High PF > 0.9 and Low THD < 30% and low Ripple < 20% 
  • Compatible With Leading-edge Dimmer and Trailing-edge Dimmer
  • Internal Protections
  • Under Voltage Lock Out (UVLO)
  • Output Open protection
  • Over Temperature Protection (OTP)
  • Pb-free SO-8 pacakge


  • Non-dimmable MR16, AR111 Lamps
  • Dimmable MR16, AR111 Lamps
  • General Illumination Lamps
