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 21):
The lighting circuit according to  claim 18 , wherein the converter controller further comprises a second error amplifier structured to amplify a difference between a fifth current detection signal that corresponds to a DC component of the coil current or otherwise a DC component of the output current and a reference signal that indicates a target value of the fifth detection signal, so as to generate a second error signal,\n and wherein the hysteresis voltage source is structured to receive the second error signal instead of the second analog signal, and to generate the upper threshold signal and the lower threshold signal determined according to the second error signal.
