AL8823

NEW PRODUCT AL8823 MR16 SINGLE BOOST LED CONTROLLER Description 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. The driver can be used for dimmable MR16, AR111 application and can be compatible with leading-edge dimmer and trailing-edge dimmer. The AL8823 is available in package SO-8. Features  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  Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2)  Halogen and Antimony Free. “Green” Device (Note 3) Pin Assignments (Top View) CS 1 FB 2 COMP 3 GND 4 SO-8 Applications  Non-dimmable MR16, AR111 Lamps  Dimmable MR16, AR111 Lamps  General Illumination Lamps 8 NC 7 OUT 6 VCC 5 VIN Notes: 1.
