AL8823 MR16 SINGLE BOOST LED CONTROLLER Description Pin Assignments The AL8823 is a boost controller that delivers an accurate constant current for MR16, AR111 and similar LED Lamps. With proprietary (Top View) 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 CS 1 8 NC applications. The operation frequency is up to 1MHz that allows the use of small size inductor. With external MOS, the AL8823 can be FB 2 7 OUT 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 3 COMP 6 VCC available in package SO-8. GND 4 5 VIN Features Wide Input Voltage Range: 5V to 36V SO-8 Continuous Conduction Mode (CCM) Operation Up to 1MHz Switching Frequency Applications High PF > 0.9 and Low THD < 30% and Low Ripple < 20% Non-dimmable MR16, AR111 Lamps Compatible with Leading-edge Dimmer and Trailing-edge Dimmable MR16, AR111 Lamps Dimmer General Illumination Lamps 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.
