Abstract:
A converter controller controls a switching converter. A current detection circuit generates a current detection signal V CS  that corresponds to a coil current I L  of the switching converter. An error amplifier amplifies the difference between the current detection signal V CS  and an analog signal V ADIM  that indicates a current to be supplied to a semiconductor light source, so as to generate an error signal V ERR . A hysteresis comparator compares the current detection signal V CS  with an upper threshold signal V THH  and a lower threshold signal V THL  determined according to the error signal V ERR , and generates a control pulse S CNT  that corresponds to a comparison result. A driver drives a switching transistor according to the control pulse S CNT .

Claim (Index 2):
The lighting circuit according to  claim 1 , wherein the threshold voltage adjustment circuit comprises a voltage source structured to generate an upper voltage and a lower voltage, and to change a voltage difference between the upper voltage and the lower voltage according to the frequency error signal,\n and wherein the hysteresis comparator comprises:\n a selector structured to receive the upper voltage and the lower voltage, and to select one from among the upper voltage and the lower voltage according to the control pulse; and \n a first comparator structured to compare the current detection signal with a threshold voltage that corresponds to an output of the selector.
