Abstract
The sawtooth wave generation circuit includes: a switch circuit configured to switch a connection state thereof between a first connection state, in which a current from a current source is flowed from a first terminal of the output capacitor to a second terminal of the output capacitor, and a second connection state, in which a current from the current source is flowed from the second terminal of the output capacitor to the first terminal of the output capacitor; a switch control circuit configured such that, in each connection state of the switch circuit, if an output voltage has reached a predetermined threshold which is set in relation to an intermediate voltage, the switch control circuit controls the switch circuit to switch the connection state to the other connection state at least during a part of a predetermined period thereafter.
