- Using TPS54x80 Tracking SWIFT(TM) dc/dc Converters f/Simult. Tkg of Input SupplyPDF, 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 - Sequencing with TPS54x80 and TPS54x73 DC/DC ConvertersPDF, 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 PackagePDF, 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 CapacitorsPDF, 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
