Title: Light emitting diode driving circuit reducing sub harmonic oscillation of driving current
Inventor: LEE SANG GUG
IPC: H05B37/02
Filed: 2015-06-10
Abstract: An LED drive circuit comprises a drive transistor, an LED block, a load resistor, an average current maintaining control unit, a sub-harmonic oscillation control unit, a logical sum operator, an inactive section control unit, and an SR latch. The LED block drives an LED by a drive current corresponding to an input voltage and outputs the drive current to a drain of the drive transistor. The load resistor includes one end connected to a source of the drive transistor and the other end to which a ground voltage is applied. The average current maintaining control unit generates a first reset signal to maintain an average value of the drive current based on a load voltage of the source of the drive transistor and a reference voltage. The sub-harmonic oscillation control unit generates a second reset signal to keep the load voltage smaller than the sum of a previous average value of the load voltage and an offset voltage. The logical sum operator generates a third reset signal by calculating a logical sum of the first reset signal and the second reset signal. The inactive section control unit activates a set signal after an output signal is inactivated and a prescribed time elapses. The SR latch receives the set signal on a set port and receives the third reset signal on a reset port to supply the output signal to a gate of the drive transistor through an output port.
