Large projects are frequently broken down into subsystem teams each of which develops their portion of the application independently of the others. In order to create a final executable all the modules from all the subsystem teams need to be combined. One way to do this is to have each subsystem team supply a linked relocatable file to the system integrator. The system integrator would then link
Bridgeless power factor correction (PFC) topology is attracting attention as a means of satisfying the new high-efficiency requirements. This application report reviews the UCC28070 and its design considerations for bridgeless PFC. It present a bridgeless solution that is relatively easy to implement in that it does not require any additional circuitry for current sensing and that the operation re
Pulse Width Modulated (PWM) signal generation is crucial to many motor and motion control applications. PWM signals are pulse trains with fixed frequency and magnitude and variable pulse width. There is one pulse of fixed magnitude in every PWM period. However the width of the pulses changes from period to period according to a modulating signal. This document discusses how to generate symmetric
The synchronous buck converter controllers (TPS56100, TPS56300, TPS56xx, and TPS5602) made by Texas Instruments are specifically designed to provide excellent transient response and high efficienty to
In digital systems data is continuously being exchanged between various subsystems. If the data arrives at differing speeds intermediate storage is necessary. This intermediate storage works on a first-in first-out (FIFO) basis. This document discusses the basics of FIFOs and gives and overview of their use in telecommunications applications in modems with data compression in DSP int
High accuracy measurements of low-level signals in the presence of high isolation mode voltages can be difficult due to the errors of the isolation amplifiers themselves.
The application report describes the design and function of a stereo high-fidelity tone control using a single TLC074 quad operational amplifier. A rail-to-rail operational amplifier is used to provide a midpoint supply voltage and signal ground allowing the use of a single power supply.
This application report examines the high-voltage lifetime characteristics of the isolation barrier in the ISO72x family of digital isolators. This provides the user with information regarding the lon
This application report describes the operation and performance of a 12-V to 2-V 20-A synchronous buck regulator evaluation design using the TPS5210 Programmable Synchronous Buck Regulator Controller. Experimental data shows tight static and dynamic regulation (?55 mV) fast transient response (within 1 micosecond) high efficiency (up to 90%) and stable operation with good noise immunity. The TP

This application report shows how to implement a single-chip thermocouple interface. The thermocouple interfaces with the MSP430F5529’s integrated 12-bit analog/digital converter (ADC12_A) through an operational amplifier circuit. The MSP430 encodes the thermocouple readings into a digital value converts them to temperature and stores them in memory.
The reference design and application examples shown in this document help design a TFT-LCD power supply as well as show implementations of power-down sequencing programmable sequencing and boosting output current.
Samples of the Texas Instruments (TI™) TMS320C6201B DSP will be available in the second half of 1998 with volume production starting at the end of the year. The TMS320C6201B revision is manufactured using a 0.18-micron process compared to the currently available revision 2 that uses a 0.25-micron process. The use of a smaller process for the TMS320C6201B DSP will lead to significantly lower
This application report is a general guide for using the CDC7005 clock synchronizer/synthesizer and jitter cleaner from Texas Instruments. This report explains the basic functionality and methods for using the device efficiently along with the results of evaluations. It also describes the clock termination method decoupling the power supply and general applications.
