Abstract
A device, a circuit, and a method for current bypass are provided. The device includes circuitry detects an overload condition at a switching regulator output, enables a current bypass path including a linear current source in response to detecting the overload condition, and digitizes a difference between a load current and a switching regulator output current. The linear current source generates an active current assist signal based on the digitized difference between the load current and the switching regulator output current.
