电源技术 电信、数据通信和工业电源产品
In industrial applications, high voltage power supply spikes with durations ranging from a few microseconds to hundreds of millisecondsare commonly encountered. The electronics in these systems must not only survive transient voltage spikes, but in many cases alsooperate reliably throughout the ev ...
电源技术 DN464 高效率USB电源管理系统
 
Automotive power systems are unforgiving electronicenvironments. Transients to 90V can occur when thenominal voltage range is 10V to 15V (ISO7637), along withbattery reversal in some cases. It’s fairly straightforwardto build automotive electronics around this system, butincreasingl ...
单片机编程 单片机P0口的片外数据存储器扩展
单片机作为一种微型计算机，其内部具有一定的存储单元（8031除外），但由于其内部存储单元及端口有限，很多情况下难以满足实际需求。为此介绍一种新的扩展方法，将数据线与地址线合并使用，通过软件控制的方法实现数据线与地址线功能的分时转换，数据线不仅用于传送数据信号，还可作为地址线、控制线，用于传送地址信号和控 ...
单片机编程 1A SIMPLE STEP-DOWN SWITCHING
The TL2575 and TL2575HV represent superior alternatives to popular three-terminal linear regulators. Due totheir high efficiency, the devices significantly reduce the size of the heatsink and, in many cases, no heatsink isrequired. Optimized for use with standard series of inductors available from s ...

教程资料 基于Xilinx FPGA的双输出DC/DC转换器解决方案
 
Xilinx FPGAs require at least two power supplies: VCCINTfor core circuitry and VCCO for I/O interface. For the latestXilinx FPGAs, including Virtex-II Pro, Virtex-II and Spartan-3, a third auxiliary supply, VCCAUX may be needed. Inmost cases, VCCAUX can share a power supply with VCCO.The ...
