Title: Switching power supply device
Inventor: FUKUSHIMA SHUN
IPC: H02M3/155
Filed: 2019-09-19
Abstract: To properly start a switching operation from a switching stop state.SOLUTION: A main control circuit (110) has a PWM comparator (CMP1) comparing comparison voltage (Vc) generated according to feedback voltage (Vfb) with ramp voltage (Vramp) whose voltage value periodically changes, and makes an output stage circuit (MM) perform a switching operation based on a comparison result in a PWM control. A feedback route switch (SW0) is inserted into a feedback route transmitting a signal according to the feedback voltage to the PWM comparator. The main control circuit, when a sleep control stopping the switching operation is switched to the PWM control, in a specific period equal to or more than a single period of the PWM control, starts the switching operation by setting voltage within a variable range of the ramp voltage as initial voltage of the comparison voltage while making a feedback route switch off, and after the specific period, controls the comparison voltage based on the feedback voltage by making the feedback route switch on.SELECTED DRAWING: Figure 1
