  • Basic Calculation of a Boost Converter's Power Stage (Rev. C)
    PDF, 186 Kb, 修订版: C, 档案已发布: 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.

  • Performing Accurate PFM Mode Efficiency Measurements (Rev. A)
    PDF, 418 Kb, 修订版: A, 档案已发布: Dec 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.
