Notas de aplicación
- Feedforward Capacitor Makes Boost Converter Fast and StablePDF, 1.0 Mb, Archivo publicado: nov 2, 2016
- TPS61040 Inverter Design (Rev. A)PDF, 56 Kb, Revisión: A, Archivo publicado: jun 9, 2003
Although designed to be a positive voltage boost converter, the TPS61040 can be configured as an inverting converter using an OPA348 operational amplifier or equivalent to invert the feedback signal. - High Voltage Power Supply Using the TPS61040PDF, 32 Kb, Archivo publicado: jul 9, 2002
The TPS61040 is a highly integrated, low power, boost converter capable of delivering output voltages up to 28 V. The addition of two small diodes and two small capacitors enables the TPS61040 to deliver output voltages up to 50 V. - TPS61042 Dual Li-Ion and Higher Input VoltagesPDF, 46 Kb, Archivo publicado: marzo 13, 2003
This document shows how to operate the TPS61042 from input voltages greater than 6 V. The ability to operate from input voltages greater than 6 V allows the TPS61042 to operate from dual Li-Ion or higher input voltages. - Minimizing Ringing at the Switch Node of a Boost ConverterPDF, 201 Kb, Archivo publicado: sept 15, 2006
The application report explains how to use proper board layout and/or a snubber to reduce high-frequency ringing at the switch node of a boost converter. - Design considerations for a resistive feedback divider in a DC/DC converterPDF, 393 Kb, Archivo publicado: abr 26, 2012

- Performing Accurate PFM Mode Efficiency Measurements (Rev. A)PDF, 418 Kb, Revisión: A, Archivo publicado: dic 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.
