MT7955 Datasheet | Maxic Technology

High Accuracy, Primary-side AC-DC LED Driver DESCRIPTION MT7955 is a primary-side controller for AC-DC LED lighting. It operates in constant current control mode and works in discontinuous conduction mode, suitable for flyback converter under universal input. MT7955 adopts primary side sensing and regulation technology, no secondary side feedback circuit is needed. Further, the loop pensation ponents are also eliminated while maintaining system stability. With building in 600V power MOSFET, low ponent counts and low BOM cost are achieved. By using Maxic proprietary current regulation method, the MT7955 achieves ±3% accuracy of LED current along with excellent line...
