摘要：This paper proposes LED driver to minimize power consumption due to LED forward voltage difference and temperature rising. Compared to conventional LED driver, the proposed driver had excellent stability, brief structure and linear output voltage of DC-DC boost converter. With the channel current set at 100mA, the on/off switchover was controlled by means of the PWM control signal in the simulation and actual installation. As a result, it turned out that the normal LED current value of 100mA was produced according to the input PWM control signal.
