Energy-feedback type LED array interface circuit

The invention discloses an energy-feedback type LED array interface circuit which is composed of n channel circuits and a multi-channel current controller with the dimming function. The channel circuit j(j=1-n) is formed by an input capacitor Cij, an inductor Lj, an N-MOS tube Mj, a diode Dj, a capacitor Caj, a coupled inductor Laj, a coupled inductor Lbj, an N-MOS tube Maj, a diode Daj and an output capacitor Coj. Being matched with the channel circuit j, the multi-channel current controller with 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 problem of inconsistency of various sub-circuits in an LED array is solved through the adjustment effect of the energy-feedback type LED array interface circuit, meanwhile, efficient LED array driving is achieved through the excess-energy collecting and feedback functions of the energy-feedback type LED array interface circuit, and the energy-feedback type LED array interface circuit is s
