应用须知

  • TPS60230 WLED Charge Pump
    PDF, 70 Kb, 档案已发布: 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.

  • 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.
