RF isolator for isolating voltage sensing and gate drivers

An apparatus, comprising:

• a single integrated circuit package for providing isolation between a controller on a first side of a switched power supply and a second side of the switched power supply;
• power transistor gate driver circuitry located within the single integrated circuit for driving power transistors on the second side of the power supply;
• at least one isolation link located within the single integrated circuit for interconnecting the first and the second sides, the isolation link providing voltage isolation between the first side and the second side of the switched power supply, wherein the isolation link further provides voltage isolation between the controller and the power transistor gate driver circuitry.

An apparatus, comprising:

• a single integrated circuit package for providing isolation between a first side of a switched power supply and a second side of the switched power supply,
• voltage sensing circuitry located within the single integrated circuit package for sensing the output voltage of the switched power supply on the second side and generating a voltage feedback signal;
• at least one isolation link located within the single integrated circuit interconnecting the first side and the second side, the isolation link providing voltage isolation between the first side and the second side, wherein the isolation link further provides voltage isolation between a controller in the first side of the switched power supply and the voltage sensing circuitry.
