Title:
POWER SUPPLY CIRCUIT DEVICE
Document Type and Number:
Japanese Patent JPS6019215
Kind Code:
A
Abstract:
PURPOSE:To secure the accurate control for the rise of the output voltage by applying the monotonous increase voltage to the input a one side of each of plural differential amplifier circuits and plural types of set voltage obtained by smoothing an output with the triangular wave voltage and the variable charge voltage define as a differential input to the input of the other side. CONSTITUTION:An input terminal at one side of each of differential amplifier circuits 12-14 is connected to an application terminal 11 of the soft start voltage to which the voltage VST increasing monotonously toward a prescribed level is applied. While voltage setting circuits 15-17 are connected to each input terminal of the other side to supply the smoothed voltage. If set voltages V15-V16 delivered from circuits 15-17 satisfy a relation V15
