Abstract:
An isolation circuit includes a low dropout operational current control loop and a shunt regulator. The current control loop is configured to drive the shunt regulator to result in a high dynamic impedance ratio between a voltage source and a load. The current control loop may include a series-pass transistor, a current sensing resistor, and a high side current sensor.
