    摘要: A control circuit of a DC-DC converter is provided. A mode selection section selects an Active Clamp Forward (ACF) or a Logic Link Control (LLC) mode. A soft start section generates a soft start signal in the ACF and LLC modes. A PWM comparison section compares a current detection signal with a feedback signal, a feedback reference signal and the soft start signal in the ACF mode, and generates a PWM signal based on a comparison result. A selection section selects the PWM signal of the PWM comparison section in the ACF mode. A clock generation section generates a clock signal having a fixed frequency in the ACF mode, and generates a clock signal having a frequency based on an operating current and the soft start signal in the LLC mode. A latch section maintains the PWM signal in response to the clock signal in the ACF mode and maintains the clock signal in the LLC mode.

    摘要: There is provided an LED circuit including a light emitting unit including a plurality of light emitting diodes; and a switching unit switching to apply only positive voltage of an AC power supply to an anode of the light emitting unit. Through this, the LED circuit can reduce complexity of a driving circuit. Further, lifespan and efficiency of the LED circuit may be improved since an electrolytic capacitor and a bridge circuit are not used. Further, any one light emitting diode may be prevented from determining the lifespan of all of the light emitting diodes since all of the light emitting diodes are driven at all times, thereby improving the lifespan of the light emitting diode.
