U-154 The New UC3879 Phase-Shifted PWM Controller Simplifies the Design
Texas InstrumentsThis application note introduces the UC3879 integrated circuit and compares its performance to that of its predecessors the UC3875/6/7/8 controller family. These integrated circuits provide all necessary control decoding protection and drive functions to successfully manage the operation of the full-bridge converter with phase-shifted control. This integrated solution greatly simplifies the de
Pushing the envelope with high-performance digital-isolation technology
Texas InstrumentsIsolation is a means of preventing DC and uncontrolled AC currents between two parts of a system, while allowing signal and power transfer between those two parts. Electronic devices and integrated circuits (ICs) used for isolation are called isolators. Isolation is required in modern electrical systems for a variety of reasons. Some examples include protecting human operators and preventing damage to expensive processors in highvoltage systems, breaking the ground loop in communication networks, and communicating to high-side devices in motor-drive or power-converter systems (Figure 1). Examples of applications that need isolation include industrial automation systems, motor drives, medical equipment, solar inverters, power supplies, and electric vehicles (EVs).
Recent advances in isolation technology are enabling new solutions, reducing system cost, and allowing customers to push the performance envelope of their equipment. This article discusses key end applications that are driving cutting-edge innovations in isolation technology and benefitting from these innovations.

Evaluation of Nickel/Palladium-Finished ICs With Lead-Free Solder Alloys
Texas InstrumentsA 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

Using PWM Output as a Digital-to-Analog Converter on a TMS320F280x (Rev. A)
Texas InstrumentsThis 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

How to Configure and Use the bq27410
Texas InstrumentsTI’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
Sequential Addressing of I/O Ports on the TMS320C54x
Texas InstrumentsOn 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
