Each DC-DC subconverter drives a separate output of the multiple-output converter and typically has a separate feedback control circuit for controlling output voltage and/or current. The converter has a common timing circuit to maintain a phase offset between the first and DC-DC subconverters. The primary energy storage inductors of the first and second DC-DC converter are magnetically coupled to raise an effective ripple frequency of the converter and simplify output filtering."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multistage and multiple-output DC-DC converters having coupled inductors","description":"A multiple-output DC-DC converter has a first and a second DC-DC sub-converter, each DC-DC subconverter may be a buck, boost, or buck-boost converter having a primary energy-storage inductor.
