Abstract
An embodiment of the present invention is a three-terminal switched mode power supply chip with a signal terminal for accepting a combination of a feedback control signal and bias supply voltage to operate the chip. A feedback extraction circuit separates the feedback signal from the power supply voltage within the chip by sensing the excess current flowing through a shunt regulator.
