a converting unit including a semiconductor control switch and an inductor; an error value generating unit to generate error value by comparing the distributed voltage from a load output terminal with a reference voltage; a multiplying unit(82) to multiply the error value and the distributed voltage from an input terminal; a comparing unit(83) to compare the output of the multiplying unit(82) with a voltage determined by the current flowing through the semiconductor control switch; and an off-time control unit(500) to control the semiconductor control switch by inputting the output signal of the comparing unit(83). |
