Abstract:
1. A method of coupling in parallel multiple voltage regulators in a power supply system to provide a combined output current, each of the multiple voltage regulators including a power output stage having a control input and an output, the multiple voltage regulators including a first voltage regulator and a second voltage regulator, the method comprising: providing a common input control voltage supplied to all of the power output stages in the system by coupling the control inputs of all of the power output stages; the control inputs being coupled such that the voltage at outputs of the voltage regulators is substantially equal; the input control voltage being provided independently from the voltage at the outputs of the voltage regulators; and coupling the outputs of the voltage regulators in parallel such that the combined output current produced is substantially equal to the sum of current produced by the voltage regulators, and each of the voltage regulators provides substantially the same current to a load connected to a common output of the voltage regulators.
