Energy-feedback LED array interface circuit

An energy-feedback LED array interface circuit is formed by n channel circuits and one multi-channel current controller having a dimming function. Each channel circuit j (j=1,...,n) is composed of an input capacitor Cij, an inductor Lj, an N-MOS pipe Mj, a diode Dj, a capacitor Caj, coupled inductors Laj and Lbj, an N-MOS pipe Maj, a diode Daj and an output capacitor Coj. The multi-channel current controller matched with the channel circuits j and having the dimming function is provided with a port vc, a port vs, a port vgj, a port vsj, a port vgaj, a port vsenj and a port vpj. The energy-feedback LED array interface circuit solves the problem that various branch circuits in an LED array are not inconsistent through a regulation effect of the LED array interface circuit, meanwhile, efficient LED array drive is achieved through collection and feedback effects of excess energy of the LED array interface circuit, and the energy-feedback LED array interface circuit is suitable for drive systems of random regular
