- Minimizing Ringing at the Switch Node of a Boost ConverterPDF, 201 Kb, Archivo publicado: sept 15, 2006
The application report explains how to use proper board layout and/or a snubber to reduce high-frequency ringing at the switch node of a boost converter. - 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. - IQ: What it is what it isn’t and how to use itPDF, 198 Kb, Archivo publicado: jun 17, 2011
- Performing Accurate PFM Mode Efficiency Measurements (Rev. A)PDF, 418 Kb, Revisión: A, Archivo publicado: dic 11, 2018
When performing measurements on DC-DC converters using pulse frequency modulation(PFM)or any power save mode proper care must be taken to ensure that the measurements are accurate. An accurate PFM mode efficiency measurement is critical for systems which require high efficiency at low loads such as in smart home systems tablets wearables and metering.
