Abstract

A control circuit for a power converter can include: a current detection circuit configured to generate a current detection signal that represents an input current; a control signal generator configured to generate a switching control signal such that the current detection signal is directly proportional to a voltage conversion function; and a power stage circuit of the power converter being controlled by the switching control signal, where the voltage conversion function is a ratio of an input voltage and an output voltage of the power converter.
