  • 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
  • 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
