Abstract
A high side controller capable of sensing input voltage and output voltage of a power conversion circuit, including: a first switch, having a control end and two channel ends, the control end being coupled to a gate signal, and one of the two channel ends being coupled to a voltage signal, wherein the voltage signal is proportional to a negative version of the input voltage when the gate signal is active; an inverting amplification circuit, having an input end coupled to the other one of the two channel ends, and an output end for providing a first processed voltage; and a first sample and hold circuit, having a control input end coupled to the gate signal, an input end coupled to the first processed voltage, and an output end for providing a first sample voltage.
