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
A nickel/palladium (Ni/Pd) lead finish for integrated circuits (IC) was introduced in 1989. In 1998 solderability test results were published on Ni/Pd-finished components using a Sn/Ag/Cu/Sb lead-free (Pb-free) solder paste and printed wiring board (PWB) pads coated with organic solderability preservative (OSP). Since then a number of other Pb-free solder alloys have been introduced.This evalu
This application report presents a method for utilizing the on-chip pulse width modulated (PWM) signal generators on the TMS320F280x™ family of digital signal controllers as a digital-to-analog converter (DAC). The method involves analog low-pass filtering the PWM signal to remove high frequency components leaving only the low-frequency content. Theoretical and experimental results are presented
TI’s Impedance Track (IT)™ fuel gauge is designed for accurately reporting battery remaining capacity and run time. It is `necessary to configure and use the gauge correctly to achieve this. The bq27410 differs from the traditional IT-based gauges which require battery chemistry information and a learning cycle to achieve high accuracy. The bq27410 does not require battery chemistry selection o
On the Texas Instruments (TI) (tm) TMS320C54x the I/O port addresses are hard-coded in the opcodes for the PORTW (I/O port write) and PORTR (I/O port read) instructions. This document discusses how the tables of data can be transferred using sequential I/O port addresses.The fact that the I/O port addresses in the PORTR and PORTW instruction are hard-coded makes reading or writing a table of
This application report demonstrates the procedure used to program the TMS320VC5503/C5506/C5507/C5509/C5509A inter-integrated circuit (I2C) peripheral module. Basic operations of the I2C including reading and writing and the initialization of the I2C bus are covered. These operations are illustrated using the I2C routines provided in the chip support library (CSL). For more information see the
