TPS6102x Boost Converter Down Conversion Mode
PDF, 159 Kb, File published: Dec 16, 2004
The TPS61020 is a highly integrated, low-power, boost converter ideally suited for portable battery-powered equipment. The integrated down conversion mode allows the boost converter to operate with the input voltage greater than the output voltage, which is normally only possible with more complicated converters.

Basic Calculation of a Boost Converter's Power Stage (Rev. C)
PDF, 186 Kb, Revision: C, File published: 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, Revision: A, File published: 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.
