MT7953 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.
