SEMICONDUCTOR INTEGRATED CIRCUIT, SWITCHING POWER SUPPLY, AND CONTROL SYSTEM

摘要

A semiconductor integrated circuit includes a current mirror having a predetermined input-output ratio and including a first transistor configured to receive an input current and a second transistor configured to output an output current, and an output transistor configured to generate a reference voltage according to the output current of the current mirror. The value of the output current is greater than the value of the input current, and the total area of one or more collector regions of the first transistor is substantially the same as the total area of one or more collector regions of the second transistor.
