The SCAN90CP02 has several design-for-test (DfT) features intended to lower development andmanufacturing test costs:

• IEEE 1149.1
• IEEE 1149.6
• StuckAt fault insertion

These features also enable fast debug and isolation of faults in fielded equipment improving theequipment availability and uptime.

This application reports provides 10 considerations for your use of an RS-485 interface.

This 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

Isolation 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.

This technical brief is an overview of the low power architectural features and design considerations of the TMS320LC54x DSP (Digital Signal Processor) family. For those with a deeper interest in low-power DSP design this technical brief also provides an overview of a more detailed application brief titled Calculation of TMS320C54x Power Dissipation TI literature number SPRA164.

This application report reviews the design steps used in the evaluation module (EVM) UCC25230EVM-754. The EVM helps evaluate the UCC25230 pulse-width modulation (PWM) controller in a forwardflyback or Flybuck™ dc-dc converter topology for a 48-V telecom bias supply. The EVM is a dual-output converter with 1500-VDC isolation between the two outputs. Each output is typically rated as 12 V and 65 m

TAS5028-5122C6EVM Application Report

The installation and configuration of a system can be a major problem for the user as a result of the wide variety of different plug-in boards and computer systems which are in use. The ISA (Industry Standard Architecture) bus is a widely used standard in the PC industry. The ISA bus architecture requires the allocation of resources. These include the I/O address space a memory address space th

This application report describes the concepts and benefits of SmartReflex™ technology implemented in the DM6467 device. Two reference power supply designs that support the SmartReflex feature are also discussed. With the SmartReflex feature enabled an average of 1W in power savings can be achieved for strong devices. The included reference designs show that additional components are requir

This application report describes the implementation of a three-phase electronic electricity meter using MSP430 4xx family of microcontrollers. The implemented functions are RMS voltage for each phase

Double data rate (DDR) bus termination power requirements bring new challenges to the power supply by requiring voltage tracking of a reference supply requiring both sourcing and sinking current and maintaining a high efficiency over a wide current range. This paper address these issues while presenting an example DDR design of 12 A of output current with voltage outputs between 0.9 V and 1.25 V

PowerWise?< Class G versus Class AB Headphone Amplifiers

Bit-reversed addressing mode normally requires that the n-element array be aligned on an n-word boundary. When n is large this may result in a large hole in the memory map. To enable more efficient use of memory a technique to use bit-reversed addressing without data alignment is presented.
