Notas de aplicación

  • Using the TPS54372 in DDR Memory/Active Bus Termination Applications
    PDF, 164 Kb, Archivo publicado: jul 11, 2002
    The integrated FET, SWIFTв„ў TPS54372 regulator from Texas Instruments is a simple and low-cost solution for DDR memory bus and other high-speed logic bus termination voltage, V(TT), applications. The TPS54372 can support output voltages as low as 0.2 V.
  • Limitations of Slew Rate on the REFIN Pin of the TPS54X72 Family
    PDF, 288 Kb, Archivo publicado: mayo 23, 2005
    Tracking dc/dc converters must track a reference voltage. However, the rate of change in the reference voltage that the output voltage can successfully track is limited. This application report presents a typical application circuit and the reasons for these limitations, along with the waveforms showing circuit performance when the reference voltage slew rates are increased above the maximum.
  • Dual Output Power Supply Sequencing for High Performance Processors
    PDF, 6.0 Mb, Archivo publicado: jul 17, 2002
    Dual voltage power supply architectures are becoming commonplace in high performance microprocessor and digital signal processor (DSP) systems. To save power and increase processing speeds, processor cores have smaller geometry cells and require lower supply voltages than the system bus voltages. Power management in these systems requires special attention. Yesterday's power management ICs and app
