MT7953 High Accuracy, Primary-side AC-DC LED Driver DESCRIPTION MT7953 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, the output power of the system should less than 5W. MT7953 adopts primary side sensing and regulation technology, no secondary side feedback circuit is needed. Further, the loop compensation components are also eliminated while main
