Abstract
A power supply controller controlling a connection between a power source and a capacitor coupled between a first node and a second node and a load circuit operating with electric charge of the capacitor, includes a first controller configured to output a first control signal in accordance with an electric potential difference between the first node and the second node, a first switch configured to couple or uncouple the capacitor to or from the load circuit in response to the first control signal, a first resistor coupled between the first node and the first controller, a second resistor coupled between a node being located between the first resistor and the first controller and a third node for outputting the first control signal, and a second switch coupled in parallel to the first resistor and putting into on or off state in response to the first control signal.
