Abstract: A switching power supply device for a ripple control system that can obtain the ripple component with the necessary amplitude without using discrete elements. On capacitor Ci of CR integrator 11, a voltage is generated corresponding to the integration value of the voltage applied to inductor Lo. The ripple voltage generated on capacitor Ci has a waveform similar to that of the ripple current flowing through inductor Lo. The voltage of capacitor Ci is converted into current Iq by voltage/current converter 12, and the current is injected in resistor R3 arranged on the transmission path of output feedback voltage VFB in comparator 2. Resistor R3 generates ripple voltage (Iqxr3) corresponding to the ripple current flowing through inductor Lo. The synthetic voltage of the ripple voltage and output feedback voltage VFB is compared to reference voltage Vref.

Abstract: The objective of this invention is to provide a DC-DC converter characterized by the fact that by correcting the loop gain corresponding to the switching of the operating mode, the variation in the output voltage that accompanies the switching of the operating mode can be minimized. Loop gain correction section 50 for correcting the gain of the feedback loop that controls output voltage VOUT is used, so that when the operating mode is switched in response to change in the input voltage VIN, the gain of the feedback loop is reduced by means of loop gain correction section 50. As a result, the duty ratio of pulse-width modulation signal VPWM1 output from pulse-width modulation portion 20 is decreased, and output voltage VOUT is controlled to be reduced. Consequently, the transient rise of output voltage VOUT that accompanies the switching of the operating mode can be avoided, the stability of the output voltage can be improved, and the influence on the load circuit can be prevented.

Abstract: An inrush current suppressing device capable of stabilizing inrush current suppression control to improve the reliability and quality of the control. A current limiting element limits an input current flowing to a power supply circuit in accordance with an input current limit value. A current detecting section detects the input current flowing through the current limiting element and converts the current to a voltage signal, and a sloping voltage signal generating section generates a sloping voltage signal proportional to a time elapsed after the start of power supply. An input current limiting section compares the voltage signal with the sloping voltage signal, and outputs the input current limit value for suppressing the inrush current while gradually increasing the limit value with rise in the sloping voltage signal during a period in which the voltage signal is higher in level than the sloping voltage signal after the start of power supply.
