  • 数控DCDC转换器在便携产品中的应用

    Abstract: This tutorial discusses methods for Digitally adjusting the output voltage of a DC-DC converter. The digital adjustmentmethods are with a digital-to-analog converter (DAC), a trim pot (digital potentiometer), and PWM output of a microprocessor.Each method is assessed and several DACs and digital potentiometers presented.

  • CAT5110 CAT5118 CAT5119 CAT512

    CAT5110/18/19/23/24/25 linear-taper Digitally programmable potentiometers perform the same function as a mechanical potentiometer or a variable resistor. These devices consist of a fixed resistor and a wiper contact with 32-tap points that are Digitally controlled through a2-wire up/down serial interface.

  • 如何测试稳压器的负载瞬态响应

      Semiconductor memory, card readers, microprocessors,disc drives, piezoelectric devices and Digitally based systemsfurnish transient loads that a voltage regulator mustservice. Ideally, regulator output is invariant during a loadtransient. In practice, some variation is encountered andbecomes problematic if allowable operating voltage tolerancesare exceeded. This mandates testing the regulatorand its associated support components to verify desiredperformance under transient loading conditions. Variousmethods are employable to generate transient loads, allowingobservation of regulator response

  • MSP430G2553

    DESCRIPTION The Texas Instruments MSP430 family of ultra-low-power microcontrollers consists of several devices featuring different sets of peripherals targeted for various applications. The architecture, combined with five low-power modes, is optimized to achieve extended battery life in portable measurement applications. The device features a powerful 16-bit RISC CPU, 16-bit registers, and constant generators that contribute to maximum code efficiency. The Digitally controlled oscillator (DCO) allows wake-up from low-power modes to active mode in less than 1 μs. The MSP430G2x13 and MSP430G2x53 series are ultra-low-power mixed signal microcontrollers with built-in 16- bit timers, up to 24 I/O capacitive-touch enabled pins, a versatile analog comparator, and built-in communication capability using the universal serial communication interface. In addition the MSP430G2x53 family members have a 10-bit analog-to-digital (A/D) converter. For configuration details see Table 1. Typical applications include low-cost sensor systems that capture analog signals, convert them to digital values, and then process the data for display or for transmission to a host system.

  • Digitally+Assisted+Pipeline+ADCs

    The continued reduction of integrated circuit feature sizes and commensurate improvements in device performance are fueling the progress to higher functionality and new application areas. For example, over the last 15 years, the performance of microprocessors has increased 1000 times. Analog circuit performance has also improved, albeit at a slower pace. For example, over the same period the speed/resolution figure-of-merit of analog-to-digital converters improved by only a factor 10.

  • 基于DSP28335+IR2110芯片的移相全桥驱动电路设计

    为解决移相全桥电路驱动及相角控制问题,设计了一种数字控制的移相全桥驱动电路.以TPL521为光耦隔离、IR2110为栅极驱动芯片.由DSP产生PWM信号,经过光耦隔离和逻辑电路后送至IR2110进行相角控制.文章对IR2110驱动电路原理进行分析及参数进行设计,对TMS320F28335进行设置并给出部分代码.实验结果表明:通过TMS320F28335可产生的不同相角的PWM波形,满足了移相全桥对不同相角控制的要求.In order to solve the problem of phase-shifted full-bridge circuit driving and phase angle control,a Digitally controlled phaseshifted full-bridge driving circuit was designed. TPL521 optocoupler isolation,IR2110 gate driver chip. PWM signals are generated by the DSP and sent to the IR2110 for phase angle control after optocoupler isolation and logic circuits. This text carries on the analysis to the principle of IR2110 drive circuit and parameter design,set up and give out some code to TMS320F28335. The experimental results show that the PWM waveforms with different phase angles generated by TMS320F28335 can meet the requirements of phase-shifted full-bridge control for different phase angles.
