    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.

    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.
