C)PDF, 186 Kb, Revision: C, Datei veröffentlicht: Jan 8, 2014
This application note gives the equations to calculate the power stage of a boost converter built with an IC with integrated switch and operating in continuous conduction mode. It is not intended to give details on the functionality of a boost converter (see Reference 1) or how to compensate a converter. See the references at the end of this document if more detail is needed. - Understanding Buck-Boost Power Stages in Switchmode Power Supplies (Rev.
