NEW PRODUCT AL8823 MR16 SINGLE BOOST LE D CONTROLLER Description The AL8823 is a boost controller that delivers an ac curate constant current for MR16, AR111 and similar LED Lamps. With proprietar y control scheme, the LED driver is com patible with many commonly used electro nic transformers and provides designs w ith High Power Factor (PF) and low Tota l Harmonic Distortion (THD) for these a pplications. The operation frequency is up to 1MHz that allows the use of smal l size inductor. With external MOS, the AL8823 can be used for wide range of o utput powers. The driver can be used fo r dimmable MR16, AR111 application and can be compatible with le

ading-edge dimmer and trailing-edge dimm er. The AL8823 is available in package SO-8. Features  Wide Input Voltage R ange: 5V to 36V  Continuous Conducti on Mode (CCM) Operation  Up to 1MHz Switching Frequency  High PF > 0.9 a nd Low THD < 30% and Low Ripple < 20% � �� Compatible with Leading-edge Dimmer and Trailing-edge Dimmer  Internal P rotections  Under Voltage Lock Out ( UVLO)  Output Open Protection  Ov er 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 (To p View) CS 1 FB 2 COMP 3 GND 4 SO-8 App lications  Non-dimmable MR16, AR111 Lamps  Dimmable MR16, AR111 Lamps � � General Illumination Lamps 8 NC 7 OU T 6 VCC 5 VIN Notes: 1.
