Application Notes
- Feedforward Capacitor Makes Boost Converter Fast and StablePDF, 1.0 Mb, File published: Nov 2, 2016
- TPS61040 Inverter Design (Rev. A)PDF, 56 Kb, Revision: A, File published: 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, File published: 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, File published: Mar 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, File published: Sep 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, File published: Apr 26, 2012

- 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.
