Patent ID: 8772967

Claim:
A multiple-output converter comprising: separate first and second DC-DC subconverters, each DC-DC subconverter selected from the group consisting of a buck, boost, buck-boost, and half-bridge converter and comprising at least one primary energy storage inductor and driving a respective power output, each DC-DC subconverter having a feedback controller for adjusting on-time of at least one switching device of the converter in response to changes in its respective power output; a timing circuit such that a switching device of the first DC-DC subconverter applies power to its primary energy storage inductor at different times than a switching device of the second DC-DC subconverter applies power to its primary energy storage inductor; wherein the power output of the first DC-DC subconverter is electrically coupled to a first output node, the power output of the second DC-DC subconverter is electrically coupled to a second output node, and the second output node is electrically different from the first output node; and wherein the primary energy storage inductors of the first and second DC-DC subconverter are magnetically coupled.
