  Using TPS54x80 Tracking SWIFT(TM) dc/dc Converters f/Simult. Tkg of Input Supply
  PDF, 115 Kb, Datei veröffentlicht: Feb 10, 2005
  High-performance signal processing devices, such as FPGAs and DSPs, require multiple power supply voltages for operation. The order and timing in which these supply outputs power up and down is usually specified. A design example using the TPS54380 is shown for the case where the power supply to be tracked is also the input voltage to the TPS54380. Information is provided for adjusting the start-u

  Designing for Small-Size, High-Freq Applications Using TPS546xx DC/DC Converters
  PDF, 646 Kb, Datei veröffentlicht: Oct 19, 2001
  This application report describes the design procedure for a small-size, high frequency application using SWIFTВ™ synchronous buck regulators. It shows that the compensation circuitry of the regulators, with the minimum size output filter and fast transient response, provides the 150-kHz unity gain bandwidth of the open feedback loop. The design is illustrated by the 6-A, DDR memory VTT track

  Sequencing with TPS54x80 and TPS54x73 DC/DC Converters
  PDF, 169 Kb, Datei veröffentlicht: Apr 14, 2003
  Design of a power supply for a high-performance point-of-load processor requires special attention to manage core and input/output (I/O) voltage sequencing, which is critical to device operation and long term reliability. The TPS54x80 devices of low input voltage synchronous-buck dc/dc converters are designed for easily implementing sequential, ratio-metric, or simultaneous sequencing schemes. F

  Optimizing the Layout of the TPS546xx for Thermal Performance (Rev. A)
  PDF, 240 Kb, Revision: A, Datei veröffentlicht: Feb 8, 2002
  This application report examines the thermal performance of different layout techniques for the TPS5461x family of 6-amp synchronous buck regulators. The TPS5461x family consists of the TPS54610, TPS54611, TPS54612, TPS54613, TPS54615, and the TPS54616. The TPS54610 has an adjustable output voltage, while the output voltages of the other devices in this family are fixed. This application note is a

  Thermal Performance of SWIFT(TM) DC/DC Converters in the 28-Pin HTSSOP Package
  PDF, 267 Kb, Datei veröffentlicht: Feb 4, 2005
  The thermal management of printed-circuit boards is complex, but must be well understood to achieve optimum performance and reliability. SWIFT(TM) dc/dc converters in the 28-pin HTSSOP package rely on an exposed lead frame die pad [PowerPAD(TM)] on the bottom of the package to provide an extremely low thermal resistance from junction to case. The thermal performance of the 6-, 9-, and 14-A SWIFT d

  Using Low Voltage SWIFT DC/DC Converters with Ceramic Capacitors
  PDF, 490 Kb, Datei veröffentlicht: Jan 8, 2003
  This application note investigates an adequate phase margin for stable operation of SWIFTв„ў regulators with the ceramic capacitors at worst-case tolerances of regulator and external parts. TI also shows how the bandwidth and gain of feedback loop impact on load-current transient-response characteristics. Measurements and analysis have shown that the voltage-mode control SWIFTв„ў regulat
