Abstract
PURPOSE: To stabilize a switching regulator controller by detecting and comparing the oscillation voltage of a standard waveform generator with charging voltage of a soft starting capacitor and operating, separately from normal soft starting time constant, smaller time constant circuit than the later by a comparator.
CONSTITUTION: The deviation output of the output from a standard waveform generator 1 from an error amplifier 3 is applied to a pulse duration modulator 2 to allow the modulated output from the modulator 2 to turn the output circuit (not shown) on or off for desired output. There is provided a comparator 7 for comparing the charging voltage of a soft starting capacitor C1 with the oscillation voltage of the generator 1. Then, a circuit of the capacitor C1 and the resistor R2 having smaller time constant than that of determining the soft starting time is composed of a switch SW separately from the time constant of determining the soft starting time for stable soft starting operation without dead time.
