Description
Pin Assignments
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.
