Notas de aplicación
- Solutions for LED Driver Overvoltage ProtectionPDF, 205 Kb, Archivo publicado: 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. - Design considerations for a resistive feedback divider in a DC/DC converterPDF, 393 Kb, Archivo publicado: abr 26, 2012

- Performing Accurate PFM Mode Efficiency Measurements (Rev. A)PDF, 418 Kb, Revisión: A, Archivo publicado: dic 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.
