Abstract
An integrated circuit for a power supply circuit of a resonant type, the power supply circuit including a resonant circuit including a coil and a capacitor coupled in series, and a switching device controlling a resonant current flowing through the resonant circuit. The integrated circuit is configured to drive the switching device, and includes: a terminal configured to receive a voltage corresponding to the resonant current; a first voltage output circuit configured to output a first voltage obtained by multiplying the voltage at the terminal by a first factor; a second voltage output circuit configured to output a second voltage obtained by multiplying the voltage at the terminal by a second factor smaller than the first factor; and a driver circuit configured to drive the switching device, based on the first and second voltages, and a feedback voltage corresponding to an output voltage of the power supply circuit.
