Abstract:
In one general aspect, an apparatus can include a controller, and a power stage coupled to the controller and configured to be coupled to a power source. The power stage is configured to deliver an output voltage to a load module in response to the controller. The apparatus also includes a reference voltage circuit coupled to the controller and configured to be grounded to a first ground voltage different from a second ground voltage associated with the load module.
