AL8822/AL8823 Dimmable LED Driver/Controller

AL8822/AL8823 Dimmable LED Driver/Controller

Diodes' AL8822 and AL8823 are a boost converter and a controller that deliver accurate constant current for MR16 and similar LED lamps. They are compatible with many commonly used electronic transformers and provide designs with high power factor (PF) and low total harmonic distortion (THD). Both are compatible with leading-edge and trailing-edge triac dimmers.

Features
  • Highly integrated controller/driver in SO-8/SO-8EP
    • Low BOM solution cost
  • Support dimmable and non-dimmable MR-16 LED lamps
    • Compatible with leading-edge and trailing-edge dimmers
  • Internal 50 V and 2 A NDMOS switch (AL8822) in SO-8EP
    • Large output power capability
  • Up to 1 MHz switching frequency
    • Small size inductor
  • High PF and low THD
    • PF > 0.9, THD < 30%, and low ripple <20%
  • Built-in undervoltage lock-out, output open-circuit protection, output overvoltage protection, and output short-circuit protection
    • Provides a complete protection function
Applications
  • Dimmable and non-dimmable MR16
  • General illumination lamps
  • AR 111 lamps
