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 compensation components are also eliminated while maintaining system stability. With building in 2A / 600V power MOSFET, low component 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 regulation and load regulation.

MT7955 provides plenty of protections, such as LED short circuit protection, LED open circuit protection, over-temperature protection, VDD over voltage protection, VDD under voltage lock-out, etc.
