摘要： A control circuit for, and method of, allowing the power supply, having a controller and an output current limit, to be operated in parallel with other power supplies and a power supply incorporating the circuit or the method. In one embodiment, the circuit includes: (1) a voltage sense subcircuit, coupled to an output of the power supply, that produces a voltage control signal that is a function of an output voltage of the power supply and a voltage proportional to an output current of the power supply and (2) a current sense subcircuit, coupled to the power supply, that produces a current sense signal that is a function of the output current of the power supply, a combination of the voltage control signal and current control signal employable to modify an output of the controller and thereby regulate said power supply and allow said power supply to continuously operate in a current limit region.
