In order to use the AMC1304 for isolated shunt sensing, it is necessary to provide power to the high-side power supply of the AMC1304. One option for this high-side power supply is to derive this power from the controller side power supply of the AMC1304 using a combination of a transformer driver such as the SN6501, a transformer, and rectification circuitry. This module covers the advantages and disadvantages of using this transformer-based power supply to power the high-side of the AMC1304.
