  • Patent number: 11005383
    Abstract: A switching power supply device includes a switching circuit including first switching elements, a rectification circuit including second switching elements, a smoothing circuit, and a controller. The controller performs switching between synchronous rectification control for driving the second switching elements and in synchronization with the switching circuit and asynchronous rectification control for driving the second switching elements independently of the switching circuit, and performs feedback control based on a normal duty on the first switching elements and the second switching elements. When the synchronous rectification control is switched to the asynchronous rectification control, the controller replaces the normal duty with a switching duty different from the normal duty and performs feedback control by the normal duty after the synchronous rectification control is switched to the asynchronous rectification control.

  • Patent number: 11005380
    Abstract: A multi-output power supply device includes an inductor, a first output terminal, a second output terminal, an FET, an FET, a chopper circuit, and a controller. The FET adjusts a current output from the inductor to the first output terminal. The FET adjusts a current output from the inductor to the second output terminal. The chopper circuit has the FET and the inductor. The FET is connected in parallel with the FET, and conducts or cuts off a current. The inductor is provided between the FET and the second output terminal. For example, the controller lowers a potential from the first output terminal by turning on the FET and sets a potential difference between a drain terminal and a source terminal of the FET to zero to suppress a switching loss when the FET is turned on.
