Title: Switching control circuit
Inventor: KOGA YOICHIRO
IPC: H02M3/155
Filed: 2019-11-15
Abstract: To provide a switching control circuit that generates a correct signal for selecting an operation mode even when sawtooth wave voltage is synchronized with an external input signal.SOLUTION: In a switching control circuit 100, when an external input signal is input, an oscillation circuit oscillates a sawtooth voltage with a frequency synchronizing with the input signal, and when the external input signal is not input, the oscillation circuit oscillates the sawtooth voltage with a predetermined frequency. A reference duty generation circuit generates a reference duty voltage by comparing the sawtooth voltage with the reference voltage according to the peak value of the sawtooth voltage. An OSCPWM generation circuit generates a PWM reference waveform voltage OSC_PWM by shaping the waveform of the sawtooth voltage. A PWM control circuit generates PWM control voltages PWM1 to PWM3 by comparing error voltages Verr1 to Verr3 and the PWM reference waveform voltage OSC_PWM. A selection circuit selects one PWM control voltage. A driving circuit drives a gate of a switching transistor by one of the PWM control voltages that is selected by the selection circuit.SELECTED DRAWING: Figure 1
