- Dual Output Power Supply Sequencing for High Performance ProcessorsPDF, 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 - Thermal Performance of SWIFT(TM) DC/DC Converters in the 28-Pin HTSSOP PackagePDF, 267 Kb, Archivo publicado: 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, Archivo publicado: enero 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
