Abstract
A power converter includes a voltage source for generating an input voltage, and a regulation circuit for generating a set of output voltages based on the input voltage. The regulation circuit regulates the set of output voltages in different manners based on whether the set of output voltages is greater or less than a set of corresponding reference voltages, respectively. If one or more output voltages are less than one or more of the corresponding reference voltages, the regulation circuit regulates only those one or more output voltages during a current regulation interval based on an error voltage related to one or more differences between the one or more output voltages and the corresponding one or more reference voltages, respectively. If all output voltages are greater than the corresponding reference voltages, the regulation circuit regulates only the output voltage associated with the largest load current during the current regulation interval.
