ADT6031 Datasheet, PDF (1/7 Pages) ADTech – LED Controller with Active PFC

Primary Side Regulation for
LED Controller with Active PFC
ADT6031
GENERAL DESCRIPTION
The ADT6031 is a high accuracy constant current mode primary side regulation controller for
dimmable LED lighting system. The control signal comes from primary side without optical
coupler to simplify application design and cost. The controller operates in BCM (Boundary
conduction mode) and in a quasi-resonant mode to provides high efficiency and to ease system
EMI design. The device has robust protection function such as LED open/short protection, over
voltage protection, over temperature protection and Under voltage lock-out. The ADT6031 is
available in SOP8 Package.
