PROBLEM TO BE SOLVED: To provide a compact backup power supply device in which the number of components is reduced.SOLUTION: A backup power supply device 200 includes a capacitor 40 and a step-up/step-down circuit 50. The step-up/step-down circuit 50 includes a step-down circuit for performing a step-down operation and a step-up circuit for performing a step-up operation. The step-down circuit comprises at least a first switching element 51 and a coil 53. The step-up circuit comprises at least a second switching element 52 and a coil 53. The backup power supply device 200 can be miniaturized by configuring parts constituting the step-down circuit portion and the step-up circuit portion so that the parts are shared.SELECTED DRAWING: Figure 2
【課題】部品点数を削減して小型のバックアップ電源装置を提供することを目的とする。【解決手段】バックアップ電源装置200は、コンデンサ40と昇降圧回路50とを有する。昇降圧回路50は、降圧動作を行う降圧回路と、昇圧動作を行う昇圧回路を有する。降圧回路は、少なくとも第1スイッチング素子51とコイル53から構成される。昇圧回路は、少なくとも第2スイッチング素子52とコイル53から構成される。バックアップ電源装置200は、降圧回路部と昇圧回路部を構成する部品を共用したものに構成して小型に実現する。【選択図】図2
