Notas de aplicación
- TPS61020 Boost Converter Start-Up and PrechargePDF, 488 Kb, Archivo publicado: enero 28, 2010
The TPS61020 is a highly integrated, low-power, boost converter ideally suited for portable battery-powered equipment. To improve start-up performance from a power-limited source such as a battery, the TPS6102x family uses different steps and modes to reduce demand on the battery. This prevents the battery bus from sagging during start-up and improves start-up operation at low voltage. - Factors That Determine Light Load PSM Switch Freq for TPS6102x Boost ConvertersPDF, 528 Kb, Archivo publicado: abr 21, 2006
- TPS6102x Boost Converter Down Conversion ModePDF, 159 Kb, Archivo publicado: dic 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. - Calculating and Measuring the No Load Input Current of the Boost ConverterPDF, 143 Kb, Archivo publicado: sept 23, 2016

- Basic Calculation of a Boost Converter's Power Stage (Rev. C)PDF, 186 Kb, Revisión: C, Archivo publicado: enero 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. - Optimizing Transient Response of Internally Compensated DC-DC Converters (Rev.

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.
