  MSP430 Interface to TPS60250 via I2C Master Software
  PDF, 499 Kb, 档案已发布: May 1, 2008
  The TPS60250 is a high-efficiency, constant-frequency charge pump dc/dc converter that can drive up to five white LEDs for a main display and up to two white LEDs for a subdisplay with regulated constant current for uniform intensity.A microcontroller (MCU) can be used to control the currents for white LEDs via the TPS60250 charge pump through a standard I2C interface, with the MCU acting as t

  Ballast Resistor Calculation – Current Matching in Parallel LEDs
  PDF, 351 Kb, 档案已发布: Apr 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

  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.
