Zusammenfassung:	An integrated circuit for controlling a boost converter. The integrated circuit includes a gate pin, a source pin, a feedback pin, a current mirror sub-circuit, and a control sub-circuit. The current mirror sub-circuit is connected to the source pin to produce an output current from a reference current flowing between the source pin and ground, the reference current being larger than the output current. The control sub-circuit is connected to the current mirror sub-circuit, the gate pin and the feedback pin to control a gate voltage provided to the gate pin based on the output current and a feedback voltage at the feedback pin.
