Title:
SWITCHING POWER SUPPLY
Document Type and Number:
WIPO Patent Application WO/2019/111564
Kind Code:
A1
Abstract:
The present invention is provided with: an input terminal and an output terminal; a voltage converter including a first switching circuit for inputting a voltage from the input terminal and a second switching circuit for outputting, from an output terminal O, a voltage obtained by converting the input voltage; a control circuit which outputs a control signal for selectively and sequentially driving the first switching circuit and the second switching circuit; and a delay circuit which, on the basis of the control signal for driving one of the first switching circuit or the second switching circuit, delays the next drive timing for the other switching circuit that is not being driven, thereby providing a dead time during which both the first switching circuit and the second switching circuit are off.
