The inhibit flip-flop(6) is set by the output signal of the first comparator(1) and is reset the output signal of the second comparator(5). The third comparator(8) makes the signal PWM by comparing the output signal of the sawtooth oscillator(7) with that of the error amplifier(3). The output switching portion(10) makes switching of the direct current power source, which passed the resistance for the current detect, by the output signal of the NAND gate(9).
