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 maintaining system stability. With building in 600V power MOSFET, low component counts and low BOM cost are achieved. By using Maxic proprietary current regulation method, the MT7953 achieves ±3% accuracy of LED current along with excellent line regulation and load regulation. MT7953 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. FEATURES Build in 600V power MOSFET 110V to 220V AC line voltage range Primary side sensing and regulation, no need of secondary side feedback High precision constant LED current (+/-3%) Cycle-by-cycle peak current control LED short-circuit/open circuit protection VDD under voltage lock-out protection VDD over voltage protection Over temperature protection Suitable for less than 5W applications Built-in leading edge blanking (LEB) Extremely minimum external components Available in SOP8 package APPLICATION GU10/E27 LED bulb, spot light 1-5W LED lighting application
