Abstract: High voltage rated isolation capacitors are formed on a face of a primary integrated circuit die. The isolation capacitors AC couple the primary integrated circuit in a first voltage domain to a second integrated circuit in a second voltage domain. The isolation capacitors DC isolate the primary integrated circuit from the second integrated circuit die. Isolated power transfer from the first voltage domain to the second voltage domain is provided through the high voltage rated isolation capacitors with an AC oscillator or PWM generator. The AC oscillator voltage amplitude may be increased for an increase in power through the high voltage rated isolation capacitors, and a larger value capacitor in the second voltage domain may provide for peak current demand from circuits in the second voltage domain.

A pair of input capacitors is coupled between the differential voltage input and the differential output and a pair of reference capacitors is coupled between the differential reference voltage input. A switching unit is controlled by a first and second phase operable during the first phase to connect a first terminal of the input capacitors with the common voltage connection and couple the first terminal of the reference capacitors with the inverted differential voltage reference; and during a second phase to connect the first terminal of the input capacitors with the differential input voltage and couple the first terminal of the reference capacitors with the non-inverted differential voltage reference
