Despite the fact that the UC3842 and the UCC3802 PWM Controllers are pin-for-pin compatible, they are not drop-in replacements for each other. Designed as the next generation '42, the UCC3809 also has

TVP5146 Anti-Aliasing Filters

This reference design is intended for designers who wish to design up to eight TMS320C6472 Digital Signal Processors into a system using a nominal input voltage of 5 V, with a flexible design using ex

This document describes considerations for migration from Texas Instruments TMS320DM6446 Digital Media System-on-Chip (DMSoC) to the TMS320DM6467 DMSoC. Both devices feature a dual-core architecture u

The TAS3001C stereo audio digital equalizer provides a serial control interface using the I2C protocol. Since the TAS3001C is more complex than the typical serial EEPROM often found on an I2C bus designers must consider additional aspects of the I2C specification. Methods of interfacing to the TAS3001C applicable to a wide variety of I2C masters are discussed.

The reliability of a semiconductor is determined by the junction temperature, which in turn is dependent on several factors including device layout and mounting, package thermal resistance, PCB layout, heat sink interface, and ambient operating temperature. This application note describes PCB layout guidelines for the best thermal performance and reports on junction temperature measurements of the TRF1123 and the TRF1223. Finally, the failure rate of the TRF1123 and the TRF1223 are calculated using measured junction temperatures and known reliability data for the MESFET process.

The TRF1123 and TRF1223 are GaAs Monolithic Integrated Circuit MMICs packaged in a low-cost, 5 mm x 5 mm, 32-lead leadless plastic chip carrier (LPCC) package. The package has an 8 mil thick copper base (paddle) that extends through the bottom of the package. The package is designed to solder reflow the paddle to a ground pad on the PCB so that a low thermal resistance and excellent RF performance is achieved. The die is attached to the copper paddle using high thermal conductivity silver epoxy: Ablestik Ablebond 84-1 LMIS. The epoxy thickness is kept to a minimum. For the junction temperature test, the die are mounted in packages which have the tops removed so that the surface of the die is visible for infrared temperature measurement.

SB-111 Mass Storage - Hard Disk

Output voltage swing output current and slew rate interact with many other specifications in operational amplifiers. This application note develops the definitions for each parameter and the relationship between important ac parameters such as large-signal bandwidth and distortion.

TPS2491 Using Hot-Swap Controllers for Reverse Powering FTT

The object file display (OFD) utility processes common object file format (COFF) files and converts the information contained in such files into XML format. This application note describes how to create a DSP boot image using COFF and XML files and a simple Perl script. The resulting image is a C source file which can be included into the host processor's application program and downloaded to th

This application note describes how to generate a 44.1 kHz audio clock using PLL4 of the LMH1983.

TPS84259 Reducing Output Ripple and Noise with the TPS84259

TSB41LV01 to TSB41AB1 Transition Document

The maximum input voltage rating of the bq243xx family is 30 V. However some customers like to do high-voltage pulse transient tests to prove its high-voltage capability and reliability from a system level. This pulse transient voltage could be as high as 45 V with 1-A output current limit and 200-µs pulse width. It is important for system designers to properly design the charging system wi

TPS62150 Using the TPS6215x in an Inverting Buck-Boost Topology /PMP/Advanced_Low_Power/Low_Power_DC-DC/2-App_Reports

This application report describes how to regulate more than two white light-emitting diodes (WLED) using the TPS61150/50A high-frequency boost converter with two regulated current outputs for driving

The operation of the Texas Instruments UCD9080 is configured using programmable (flash) memory within the device. The memory can be written and read using a command protocol over a standard I2C bus interface. This document provides the hardware and software details necessary to program the UCD9080 with the configuration data. TI recommends that the configuration data be developed using the UCD9080

Configuring Security and Bootloader (BSL) on MSP432P4xx

The very low oscillator (VLO) is a clock source included in the 2xx family of devices. This library provides a method of measuring the speed of the VLO without using any external components such as a 32-kHz crystal. Once measured the VLO can be used to trigger periodic interrupts with greater accuracy. Measuring the VLO also allows for setting the DCO to a specific frequency using a software FLL.

A prototype system for the receive signal chain of an ultrasound system is described. This prototype system is available to customers as an evaluation module that can be ordered from TI's Web site.
