Filed: 2011-03-31
Abstract: PROBLEM TO BE SOLVED: To provide a switching power supply device having a continuous oscillation mode and an intermittent oscillation mode which suppresses a transition to the intermittent oscillation mode during a transition of a started load to a stationary state.SOLUTION: A switching power supply 100 has a continuous oscillation mode and an intermittent oscillation mode to keep power supply efficiency intact in a standby state while supplying power to a load with a large difference between a maximum load and a minimum load. The switching power supply 100 tends to transition once from the continuous oscillation mode to the intermittent oscillation mode just after the load is started. The switching power supply 100 thus forcibly maintains the continuous oscillation mode during a transition of the load from a started state to a stationary state. This can suppress a transition of the switching power supply 100 from the continuous oscillation mode to the intermittent oscillation mode once just after the load is started.
