1. A voltage feedback circuit for low side and high side power devices arranged in a half-bridge configuration for providing an output power signal, the output power signal depending on voltages across the low and high side power devices, the voltage feedback circuit comprising:

  • sensing circuitry that senses voltage changes across the low and high side power devices;

    the sensing circuitry providing low and high side sense signals, the low side sense signal indicating when voltage changes across the low side power device and the high side sense signal indicating when voltage changes across the high side power device.
