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.
