Abstract:
A voltage compensation driving circuit is provided. The voltage compensation driving circuit converts input power into output power and auxiliary power. The voltage compensation driving circuit provides a boost control signal according to an output current of the output power, and the boost control signal has a duty cycle corresponding to the output current. The voltage compensation driving circuit boosts the auxiliary power by the boost control signal to generate a compensation voltage and transmits the compensation voltage to a light emitting device string via a boost resistor, so as to linearly control a brightness of the light emitting device string.
