MT7968AL

Maximizing IC Performance MT7968AL High Precision, Dual Winding PSR AC-DC LED Driver DESCRIPTION MT7968AL is a high precision primary-side feedback and regulation controller for LED lighting. It regulates precisely LED current in isolated lighting application. MT7968AL works under Discontinuous Conduction Mode (DCM). It simplifies LED lighting system by eliminating the secondary sense, the auxiliary winding and feedback circuit. Integrated with 600V power switch, the adjustable LED open-circuit protection (OVP) function simplifies the system design and improves the reliability. With Maxic’s proprietary current regulation and internal compensation technique, the MT7968AL achieves ±5% accuracy of LED current along with excellent line regulation and load regulation. It is also non-sensitive to the inductance of the transformer. MT7968AL provides various protection features to improve the system reliability, including over current protection (OCP), short circuit protection (SCP)，ove...
