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.

A bipolar 12V supply from a single +5V input can be developed using a number of conventional approaches. A boost converter is the most logical for the +12V output; however, it cannot be used in some i

This application report presents a method for interfacing the TLC320AD535 and TLC320AD545 codecs from Texas Instruments (TI)(tm) with the multichannel buffered serial port (McBSP) on TI's C54xx family of digital signal processors (DSPs). As is the case with many codecs from TI these devices utilize a primary and secondary communication protocol to differentiate between actual signal data and code

This application note provides a table to aid in selecting the right TPS6420x option for your application.

This document discusses how many cycles it takes the DMA to read/write to external memory. Several tables are given to allow the developer to determine this information for several different types of configurations.

This document discusses how to view the peripheral registers on a 'C240 or 'F240 device while running the emulator. It includes a lengthy code example.

This application report presents a solution to interfacing the ADS7881 12-bit parallel interface converter to the TMS320C6713 DSP. The hardware solution is made up of existing hardware specifically the ADS7881EVM 'C6713 DSK and the 5-6K Interface Board. The software demonstrates how to use an EDMA ping-pong buffer and Timer1 peripherals to collect data at 4 MSPS. Discussed also are some of the
