AL8820
40V, 2A BOOST/BUCK LED DRIVER
Description
Pin Assignments
(Top View)
The AL8820 is a highly integrated high performance LED driver
optimized for MR16/AR111 and other similar LED lamp applications.
With a proprietary control scheme, the LED driver is compatible with
many commonly used electronic transformers and meets High Power
Factor (PF) and low Total Harmonic Distortion (THD) requirements for
these applications.
The device integrates two DC/DC converters. The Two stage design
offers superior performance for MR16/AR111 applications. The first
stage is a boost PFC stage which improves PF, reduces EMI, powers
up the Buck stage and the compatibility of Electronic Transformers.
The Buck stage regulates the LED current thru the setting of external
sense resistor. The integrated low RDSON of integrated MOSFETs
reduce the conduction power loss. A compact thermally efficient SO8EP package, the AL8820 provides an ideal solution for MR16/AR111
applications.
