Application Notes
- TPS60230 WLED Charge PumpPDF, 70 Kb, File published: Nov 9, 2005
The TPS60230 is a complete solution for driving up to five white light-emitting diodes from a single-source Li-ion battery or power source up to 6.5 V. This application report breaks the part down into functional blocks and describes each of the blocks. Additionally, applications for improving current accuracy and overall efficiency, and reducing noise susceptibility are discussed. - Extending the Soft Start Time Without a Soft Start Pin (Rev.

- 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.
