7 / 28 page Embedded Power for Business-Critical Continuity Technical Reference Note Output Capacitance TheLGA C Serieshasoutputcapacitorsinsidetheconverter. Limited output capacitance,10uFforthe 3A/6A/10Aand50uFforthe20A, is required for stable operation. Whenpoweringloadswithlarge dynamiccurrentrequirements,improvedvoltageregulationis obtained by inserting low ESR capacitors ascloseaspossibletotheload. Low ESR ceramiccapacitorswillhandletheshortdurationhigh frequencycomponentsofthedynamiccurrentrequirement. Inaddition,highervaluesofelectrolytic capacitorsshouldbeusedtohandlethemid-frequencycomponents. Itisequallyimportanttousegooddesignpracticeswhenconfiguringthedcdistributionsystem.
