Differences between Startup Timing for TMS470R1x Flash and ROM Controllers
Texas InstrumentsThis document describes the differences in the startup timing between flash and the ROM controller when using the same application software. The calculation of the difference in the startup timing behavior of a flash vs. a ROM controller is shown in an example. A method to minimize the startup behavior is described.

Synchronizing Three or More UCC28950 Phase-Shifted, Full-Bridge Controllers
Texas InstrumentsOne of the key features of the UCC28950 phase-shifted, full-bridge controller is its ability to synchronize its main oscillator to an external clock source. In this way, multiple controllers can be synchronized to improve performance criteria of the end power supply. This application report expands the details of the synchronization capability of the UCC28950, provides examples of simple circuits used to generate the proper clock inputs to the UCC28950, and gives examples of the input and output signaling that can be expected with three- and four-phase applications.

AN-2292 Designing an Isolated Buck (Fly-buck) Converter (Rev. B)
Texas InstrumentsIn many applications, one or more low-cost, simple to use, isolated power supplies working from input voltages up to 100V are needed. Traditional solutions use flyback converters to generate this bia
Digital PLL Design Using the SN54/74LS297 (Rev. B)
Texas InstrumentsThe SN54/74LS297 performs a first-order PLL function with a high degree of accuracy and a minimum of external components. Features include entirely digital design accuracy with varying temperatures and voltages digitally programmable bandwidth and center frequency narrow bandwidth ripple cancellation and cascading capabilities for high-order loops. This document provides a device description
TMS320TCI6482 Design Guide and Comparisons to TMS320TCI100 (Rev. B)
Texas InstrumentsThis document describes system design considerations for the TMS320TCI6482 (TCI6482). It also gives comparisons to designing with the TMS320TCI100 (TCI100) for those familiar with that device. The objective of this document is to cover system design considerations for the TCI6482. Those familiar with the TCI100 can use the comparisons to migrate a TCI100 design to the TCI6482. In some cases there
Introduction to Code Composer Studio Plugins
Texas InstrumentsA Code Composer Studio plugin allows for the extension or customization of the development and debug environment. The plugin can be a standalone Windows application or an ActiveX control. This application note describes the process of writing a plugin and includes the source for a simple plugin.
Configuring Emulation Parameters in Code Composer Studio v2.0
Texas InstrumentsThis application report describes how to configure Code Composer Studio? Integrated Development Envornment (IDE) v2.0 to work with different emulation parameters. In versions of Code Composer Studio prior to v2.0 these parameters were set through environment variables. With Code Composer Studio v2.0 and greater the environment variables have been replaced by platform-independent configure variab

Reading a 16-Bit Bus With the TMS320C5x Serial Port
Texas InstrumentsIt is possible to read data directly from a parallel bus. Each word is loaded by a signal for example /WE. In order to read this kind of word with a synchronous serial port it has to be converted in series and synchronized by a transmission clock. The solution presented in this document uses the clock signal coming from the DSP although an independent clock source could be implemented successfu

Stacking Multiple bqq2941x Li-Ion Secondary Voltage Protectors
Texas InstrumentsLi-ion battery applications requiring five or more series cells can make use of standard 4-series-cell secondary protectors such as the bq2941x series. The devices can be stacked as necessary and outputs of individual devices can be combined with optocouplers to produce a single alarm signal if any cell exceeds the threshold. In addition for undervoltage protection TLV3011 nanopower comparato
Shared Memory Interface With a TMS320C5x DSP

Implementing V.32bis Viterbi Decoding on the TMS320C62xx DSP
Texas InstrumentsThis paper describes the implementation of the V.32bis decoding algorithm on the Texas Instruments (TI) TMS320C62xx digital signal processor (DSP). The V.32bis Viterbi decoder algorithm is based on a soft-decision maximum-likelihood decoding technique. (Details on the theory behind this algorithm are described in the TI publication DSP Solutions for Telephony and Data/Facsimile Modems literature
