When a dc/dc converter providing a regulated output voltage between the minimum and maximum input voltage is required, neither a single buck or a boost converter can provide the output voltage. However, a boost converter integrated circuit (IC) can be configured to drive a single-ended, primary-inductor converter (SEPIC) power stage and provide an output voltage that is between the input voltage e - Input Current Limit Solution for USB-Supplied Power SystemPDF, 666 Kb, Archivo publicado: agosto 3, 2017

The TPS6116x, TPS6118x and TPS6119x WLED driver and TPS6117x boost converter integrated circuits (IC) can operate with different input voltages, one powering the IC itself and the other powering the boost power stage. This application report explains various options on how to use the WLED drivers with split power rails. This allows these LED drivers to be used in applications where the available - Design of UVLO for LM27313 (Rev. B)PDF, 142 Kb, Revisión: B, Archivo publicado: abr 8, 2014

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.
