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 7):
The lighting circuit according to  claim 1 , wherein the converter controller is structured to receive a pulse dimming signal that has been pulse modulated according to a target light amount for the semiconductor light source, and to alternately repeat an operating period in which the switching transistor is switched on and off and a suspension period in which the switching is suspended,\n and wherein, during the suspension period, the threshold voltage adjustment circuit holds the frequency detection signal at a level that has been set in the immediately previous operating period.
