Title:
POWER SOURCE CONTROL DEVICE AND HEAD-UP DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/033718
Kind Code:
A1
Abstract:
Provided is a power source control device that constitutes an electronic device installed in a vehicle and controls the supply of voltage to a target of voltage supply. The power source control device is provided with a step-down circuit (61) and a step-up circuit (67). The step-down circuit is interposed between a power source and the target of supply, and steps a power source voltage of the power source down to a step-down voltage that is lower than a voltage value obtained by deducting a voltage step-down quantity due to brown-out from the voltage of the power source. The step-up circuit is interposed between the step-down circuit and the target of supply, and steps the step-down voltage outputted by the step-down circuit to a step-up voltage that does not exceed a rated voltage of the target of supply.
