Description
The FAN7346 is an LED current-balance controller that controls 4-LED arrays to maintain equal LED current.
The FAN7346 has a high withstanding voltage, so is suitable for edge-type LED BLU and LED Lighting. To minimize components between primary to secondary, the FAN7346 generates a new integrated feedback signal.
