ABSTRACT:
In an embodiment, a circuit device includes a network interface responsive to a powered network to receive a power supply and data and includes an electrical isolation barrier adapted to define a non-isolated power domain and an isolated power domain. The circuit device further includes a first control circuit associated with the non-isolated power domain. The first control circuit is coupled to a primary winding of a transformer to control current flow via the primary winding. The circuit device also includes a second control circuit associated with the isolated power domain. The second control circuit is coupled to a secondary winding of the transformer and is adapted to detect a power error associated with the secondary winding. The second control circuit transfers a command across the electrical isolation barrier to the first control circuit to adjust a current at the primary winding in response to detecting the power error.
