Abstract
A voltage converter includes a power switching unit and an indirect sensing circuit. The power switching unit includes a plurality of power switches and a capacitor. The indirect sensing circuit receives an input voltage, a first voltage at a first node of the capacitor, and a second voltage at a second node of the capacitor, and generates first and second sensing output voltages based on the input voltage and the first and second voltages. A voltage difference between the first and second voltages is equal to a fractional multiple of the input voltage.
