Notas de aplicación
- Ballast Resistor Calculation – Current Matching in Parallel LEDsPDF, 351 Kb, Archivo publicado: abr 16, 2009
Engineers often need to connect LEDs in parallel. Ideally, the LEDs share current equally. In reality, even LEDs from the same production lot have poorly matched I-V characteristics. This mismatch causes the LEDs to not share the current equally. The engineer can add a ballast resistor in series with each LED to minimize current differences. This application report explains how to size the ball - Extending the Soft Start Time Without a Soft Start Pin (Rev. B)PDF, 387 Kb, Revisión: B, Archivo publicado: jun 15, 2017
- 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.
