Anwendungshinweise
- TPS6102x Boost Converter Down Conversion ModePDF, 159 Kb, Datei veröffentlicht: 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. - Factors That Determine Light Load PSM Switch Freq for TPS6102x Boost ConvertersPDF, 528 Kb, Datei veröffentlicht: Apr 21, 2006

- Performing Accurate PFM Mode Efficiency Measurements (Rev. A)PDF, 418 Kb, Revision: A, Datei veröffentlicht: 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.
