Voltage applying circuit
First Claim
1. A voltage applying circuit provided between a DC/DC converter which lowers a first voltage to generate a second voltage and a load circuit to which the second voltage is to be applied, comprising:
- a first terminal to which the first voltage is to be applied;
a second terminal connected to the load circuit;
a plurality of capacitors; and
a switch circuit which connects the plurality of capacitors in series between the first terminal and a point of a ground voltage, when the load circuit is in a standby state, and which connects the plurality of capacitors in parallel between the second terminal and the point of the ground voltage, when the load circuit is in an active state.

Abstract
A voltage applying circuit is provided between a DC/DC converter which lowers a first voltage to generate a second voltage and a load circuit to which the second voltage is to be applied. The voltage applying circuit includes a first terminal to which the first voltage is to be applied, a second terminal connected to the load circuit, a plurality of capacitors, and a switch circuit. The switch circuit connects the capacitors in series between the first terminal and a point of a ground voltage, when the load circuit is in a standby state, and connects the capacitors in parallel between the second terminal and the point of the ground voltage, when the load circuit is in an active state.
