  • Patent number: 8829864
    Abstract: A current driver circuit includes a converter part having a switching element and converting an input voltage into an output voltage; a current detector which generates a detection signal indicative of the current of the switching element; an input voltage compensating circuit which generates a compensation signal corresponding to the input voltage; a comparator which compares the detection signal and the compensation signal against each other; and a switch driver circuit which generates a drive signal. The drive signal turns the switching element off in accordance with an output of the comparator, and turns the switching element on again after a lapse of a prescribed time from the switching element being turned off.
