グレギユレータ。 The first and second switching transistors are connected in parallel to the power supply line to which the input voltage to be regulated is supplied, and the regulated output voltage obtained at the output terminal is compared with a reference voltage by a comparator. The PWM modulator is controlled based on the comparison output to form a PWM output that corresponds to fluctuations in the output voltage, and this PWM output is
The PWM output is supplied to a first drive transistor connected to one end of the primary coil, and the PWM output is supplied via a phase shifter to a second drive transistor connected to the other end of the primary coil. . A chopper switching regulator, wherein the first and second transistors are time-divisionally controlled by switching pulses obtained on the secondary side of the drive transformer.
