AX9370 Universal High Brightness Led Driver  GENERAL DESCRIPTION The AX9370 is a high performance LED lighting controller with PFC integrated which uses primary-side-control to eliminate opto-coupler and simplify the LED lighting driving system. AX9370 removes the need for secondary feedback circuitry while achieving excellent line regulation. AX9370 integrates power factor correction function and works in boundary conduction mode (BCM) which can minimize the switching loss, thus increasing efficiency. In a flyback circuit with the controller AX9370 at BCM operation can also reduce choke variation and enhance the LED current accuracy for line input voltage variation and output voltage variation. Compared with a traditional LED driver IC, AX9370 can achieve the PF>0.
