Understanding Boost Power Stages In Switchmode Power Supplies
Texas InstrumentsA switching power supply consists of the power stage and the control circuit. The power stage performs the basic power conversion from the input voltage to the output voltage and includes switches and the output filter. This report addresses the boost power stage only and does not cover control circuits. The report includes detailed steady-stage and small-signal analysis of the boost power stage o
Power Supply Sequencing Solutions for Dual Supply Voltage DSPs (Rev. A)
Texas InstrumentsThis application report describes power-supply sequencing recommendations and techniques applicable to dual supply voltage DSPs in TI's TMS320C2000 TMS320C5000 and TMS320C6000 families. These techniques take advantage of the reset power good enable and soft-start features available on TI Power Management Products including low drop out regulators switching power supply controllers supply vol
TMS320C6000 McBSP Initialization (Rev. C)
Texas InstrumentsThe TMS320C6000? multichannel buffered serial port (McBSP) can operate in a variety of modes as per application requirements. For proper operation the serial port must be initialized in a specific order. This document describes the initialization steps necessary when either the (E)DMA or the CPU is used to service the McBSP data. Typically the (E)DMA is used to perform read/write transfers from

Using an LVDS Receiver with TIA/EIA-422 Data (Rev. A)
Texas InstrumentsReceipt of data from a TIA/EIA-422 line driver can be accomplished by using a TIA/EIA-644 line receiver with the addition of an attenuator circuit. This technique gives the user a very high-speed low-power 422 receiver.If ground noise between the transmitter and receiver is not a concern (less than +/-1 V) a resistor divider circuit can be placed in front of the LVDS receiver to attenuate th
Steam-Age Evaluation of Nickel/Palladium Lead Finish for Integrated Circuits
Texas InstrumentsRemoval of lead (Pb) from finished integrated-circuit(IC) packages as well as IC package assembly and printed circuit board(PCB) assembly operations is an ongoing effort by many electronics manufacturers.Toward this end the semiconductor industry is converting to nickel/palladium (Ni/Pd)-finished leadframes in the assembly of integrated circuits.
