Abstract:
1. A power supply system comprising: a power converter comprising a switching stage to conduct an output current in response to switching signals having a predefined duty-cycle, the output current being provided at an output of the power converter; a current monitor to sense a magnitude of the output current; a gate drive controller to generate and to control a magnitude of the switching signals and to control an output impedance of the switching stage based on the sensed output current to control the magnitude of the output current; a second power converter comprising a second switching stage to conduct a second output current in response to second switching signals, the second output current being provided to generate a second output voltage at an output of the second power converter; a second current monitor to sense a magnitude of the second output current; and a current comparator to compare the magnitude of the output current with the magnitude of the second output current, such that the gate drive controller is to control the output impedance of the switching stage based on the comparison to control the magnitude of the output current.
