Understanding Buck Power Stages In Switchmode Power Supplies
PDF, 173 Kb, Archivo publicado: marzo 4, 1999
A switching power supply consists of the power stage and the control circuit. The power stage performs the basic power conversion from the input voltage to the output voltage and includes switches and the output filter. This report addresses the buck power stage only and does not cover control circuits. Detailed steady-state and small-signal analysis of the buck power stage operating in continuous

Basic Calculation of a Boost Converter's Power Stage (Rev. C)
PDF, 186 Kb, Revisión: C, Archivo publicado: enero 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.
