Abstract
A semiconductor integrated circuit includes a first backflow prevention circuit provided on a first power line between a first AC filter and a first power output terminal, a bypass line that bypasses the first backflow prevention circuit, a charge pump circuit provided on the bypass line, and a control circuit configured to operate the charge pump circuit such that a current flows into the bypass line and the first power output terminal, when an input voltage between a first power input terminal and a second power input terminal is lower than a first threshold voltage.
