Title: Control device of switching power supply device
Inventor: YUZAWA TAKESHI
IPC: H02M3/28
Filed: 2019-01-15
Abstract: To provide a switching power supply device capable of burst control that achieves both high efficiency at light load and noise suppression.SOLUTION: The efficiency of a switching power supply device is improved by performing burst control when a load is light. In a burst control switching period, a control circuit 25 generates a first pulse that becomes a low-side output signal lo_pre, a second pulse that becomes a high-side output signal hi_pre, and a third pulse that becomes a low-side output signal lo_pre. A three-pulse control circuit 22 outputs a signal that turns off the first to third pulses. A VS bottom control circuit 23 outputs a signal that turns on the first pulse in the next switching period when the bottom number of a ringing voltage generated in a switching stop period after the third pulse has been turned off reaches a predetermined number. Since the number of resonance cycles is fixed to the predetermined number and does not coexist, sounding is suppressed.SELECTED DRAWING: Figure 2
