The most common approach to load switching solutions is to use a Power MOSFET surrounded by discrete resistors and capacitors; however, in most cases using a fully integrated load switch has significa

DN608 -- Design Notes

This application report demonstrates the procedure used to program the TMS320VC5509 digital signal processor (DSP) Real Time Clock (RTC). Basic operations of the RTC such as reading and writing the time as well as interrupt configuration are covered. All interaction with the peripheral is accomplished using the Chip Support Library (CSL) RTC module. An example that illustrates usage of these ro

The TPS5402 device is a non-synchronous buck regulator with a wide operating range from 3.5 to 28 V.The switching frequency of the converters can be set from 50 kHz to 1.1 MHz with an external resistor.Frequency-spread spectrum operation is introduced for EMI reduction. TPS5402 supports pulse-skippingmode to enhance the efficiency at light load making this device an ideal pick for applicati

This document describes how to perform data companding with the TMS320C6000(tm)digital signal processors(DSP). Companding refers to the compression and expansion of transfer data before and after transmission respectively.The multichannel buffered serial port (McBSP) in the TMS320C6000 supports two companding formats: mu-Law and A-Law. Both companding formats are specified in the CCITT G.711

AN-949 Interfacing the LM12454/8 Data Acquisition System Chips to the 80C51 Family of Microcontrollers

Power supply systems for most of today's latest applications must be able to manage how multiple outputvoltages rise after input power is applied. These power supplies must also be capable of starting up intopreexisting external voltages present at the output. Another important requirement is supply voltagemargining i.e. the ability of the power supply to momentarily adjust the output volt

This design note describes the UCC3954 evaluation kit which allows the designer to evaluate the performance of the UCC3954 Single-Cell Lithium-Ion to +3.3V Converter. The UCC3954 along with a few external components develops a regulated +3.3V from a single lithium-ion battery in which terminal voltage can vary between 2.5V and 4.2V. The UCC3954 uses a simple flyback (buck-boost) technique to co

The DSP Controller TMS320F240 from Texas Instruments is suitable for a wide range of motor drives. TMS320F240 provides a single chip solution by integrating on-chip not only a high computational power

IMPLEMENTING A HARDWARE MONITOR USING THE TMS320C40 ANALYSIS MODULE AND JTAG INTERFACE FOR PERFORMANCE MEASUREMENTS IN A MULTI-DSP SYSTEM

The AM18xx devices use a great deal of internal pin multiplexing to allow the most functionality in the smallest and lowest cost package. This software allows the pin multiplexing registers of the device to be calculated with ease as well as showing what peripherals can be used together and what devices support the peripherals that are selected. This software is useful to anyone creating a system

Fault tolerance transient protection and interference rejection are valuable features that isolation amplifiers bring to critical circuitry. Two useful examples of how designers can employ isolation amplifiers to improve their systems? performance and reliability are process temperature controllers and electrocardiogram (ECG) amplifiers.

Code Composer Studio Integrated Development Environment v4 is a major new release based on the Eclipse open source software framework. The Eclipse software framework is used for many different applications but it was originally developed as an open framework for creating development tools. We have chosen to base CCStudio v4 on Eclipse as it offers an excellent software framework for building soft

The TPS61060, TPS61061, and TPS61062 are efficient white light-emitting diode (WLED) drivers. These ICs also can be configured as a constant voltage power supply. When in constant voltage mode, the TP

This application bulletin explains how to retrieve data from the DDC112. It elaborates on the discussion given in the DDC112 data sheet and provides additional information to allow you more flexiblity during retrieval. It is assumed that you have a basic understanding of the DDC112's operation.

This application report outlines the implementation of a CPE remote management scheme using the clear EOC Channel. The capabilities of the Clear EOC Channel are discussed for G.dmt different framing mode as well as ADSL2. This application report is meant to be used to provide a basic understanding of the Clear EOC channel and how it might be used for ADSL CPE remote management.

The inter-integrated circuit (I2C) is a multi-master multi-slave single-ended bus that is typically used forattaching lower speed peripheral ICs to processors and microcontrollers. The type of slave devices range from non-volatile memory to data-acquisition devices like analog-to-digital converters (ADC) sensors and so forth. This application report demonstrates how to use the feature rich I
