Application Notes
- TPS61059 powers white-light LED as photoflash or movie lightPDF, 153 Kb, File published: Jul 17, 2006
- Flashlight & Movie-Light Supplies Using TPS61058 & TPS61059 Sync Boost ConverterPDF, 144 Kb, File published: Jun 13, 2006
The application examples and reference designs shown in this document can be used to design flashlight and movie-light applications for 1.8-V and 2.8-V logic. The TPS61058/9 devices are optimized for driving high-power, single-cell white LEDs up to 800 mA from a 2.7-V to 5.5-V input. The LED current can be programmed to different levels (e.g., torch, flashlight) by a set of external resistors.

- 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.
