Limitations of Slew Rate on the REFIN Pin of the TPS54X72 Family
PDF, 288 Кб, Файл опубликован: 23 май 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 Мб, Файл опубликован: 17 июл 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
