MT7968A

MT7968A High Precision, Dual Winding PSR AC-DC LED Driver DESCRIPTION MT7968A is a high precision primary-side feedback and regulation controller for LED lighting. It regulates precisely LED current in isolated lighting application. MT7968A 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 and 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 MT7968A 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. MT7968A provides various protection features to improve the system reliability, including over current protection (OCP), short circuit protection (SCP)，over voltage protection (OVP) and ov...
