应用须知
- Clamshell Phone w/OLED/LCD Screen Using the TPS61140 Dial Output Boost RegulatorPDF, 49 Kb, 档案已发布: Jul 6, 2006
The TPS61140/1 is a dual output boost converter providing regulated voltage and current output with one boost converter. The reference design and application example shown in this document can be used to power a clamshell phone with an organic light-emitting diode (OLED) and a LCD screen. This device is ideal for driving the OLED sub display and WLED backlight for the LCD main display in clamshell - Minimizing Ringing at the Switch Node of a Boost ConverterPDF, 201 Kb, 档案已发布: 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. - Optimizing Transient Response of Internally Compensated DC-DC Converters (Rev. A)PDF, 1.1 Mb, 修订版: A, 档案已发布: May 11, 2015

- Performing Accurate PFM Mode Efficiency Measurements (Rev. A)PDF, 418 Kb, 修订版: A, 档案已发布: 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.
