ABSTRACT:
A DC—DC converter that receives input of a direct current voltage such as a battery and supplies a controlled direct current voltage to a load is simplified. It comprises a voltage step-down converter section consisting of a first switch2, a first rectifying means3and an inductor4, a voltage step-up converter section consisting of an inductor4, a second switch5and a second rectifying means6, and a control section consisting of an output capacitor7, an error amplifying circuit10, an oscillation circuit11and a pulse width control circuit12. An oscillation voltage Vt from the oscillation circuit11is compared with an error voltage Ve from the error amplifying circuit10and a duty ratio of each switch is adjusted to control the operation of voltage step-down, voltage step-up and step-down, and voltage step-up.
