Title:
POWER SUPPLY CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/190790
Kind Code:
A1
Abstract:
A power supply control device (10) comprises a voltage conversion unit (30), a first switch (51), and a voltage step-down unit (31). The voltage version unit (30) converts a voltage between a second conductive path (42) and a third conductive path (43). The first switch (51) switches between an on-state in which the flow of a current from a first conductive path (41) to the second conductive path (42) is allowed and an off-state in which the flow thereof is blocked. The voltage step-down unit (31) comprises a voltage step-down circuit (32) that steps down the voltage applied to the third conductive path (43) and outputs the stepped-down voltage. The voltage step-down unit (31) causes a current based on the output voltage from the voltage step-down circuit (32) to flow to the second conductive path (42) if the voltage applied to the second conductive path (42) has fallen to such a degree as to reach a prescribed value not more than the output voltage from the voltage step-down circuit (32).
