应用须知

  • Solutions for LED Driver Overvoltage Protection
    PDF, 205 Kb, 档案已发布: Jun 8, 2009
    Boost LED drivers are often used to drive LEDs in series. If an LED fails while open, overvoltage protection (OVP) is necessary to avoid the damage to a boost integrated circuit (IC) or output capacitor. This application report presents the solutions to increase the TPS61043 LED driver OVP threshold.

  • 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.
