  • PW2205-2.0.pdf规格书下载

    PW2205 develops a high efficiency synchronous step-down DC-DC converter capable of delivering5A output current. PW2205 operates over a wide input voltage range from 4.5V to 30V andintegrates main switch and synchronous switch with very low RDS(ON) to minimize the conductionloss.PW2205 adopts the instant PWM architecture to achieve fast transient responses for high step downapplications and high efficiency at light loads. In addition, it operates at pseudo-constant frequencyof 500kHz under continuous conduction mode to minimize the size of inductor and capacitor

  • 一种车载充电器的设计

    以AT89S52单片机为控制核心,采用电容降压技术,Buck电路拓扑,PWM驱动模块和功率器件散热设计,通过高速的数据采集、主功率输入输出模块和控制模块,设计一种新型智能车载充电器.在充电过程中,通过负脉冲瞬间放电实现对铅酸蓄电池的再生修复,提高电池的有效容量,延长使用寿命.该充电器体积小、速度快、效率高、可靠性好.With AT89S52 single chip computer as the control core,a new type of intelligent car-carried charger was designed by using capacitance step-down technology,Buck circuit topology,PWM driving module and power device heat dissipation design,through high-speed data acquisition,main power input and output module and control module.In the charging process,the regeneration and repair of lead-acid batteries are realized by instantaneous discharge of negative pulse,which improves the effective capacity of batteries and prolongs their service life.The charger has the advantages of small size,fast speed,high efficiency and good reliability.

  • RTS5411 PCB文件

    2011年,Realtek(瑞昱)开发出了业界公认的低功耗,高性能的USB3.0 Hub 主控,RTS5401-GR。它超小的体积(QFN76)和规范化的设计(USB IF认证,BC1.2和支持苹果设备快充),赢得了行内一致认可。如今,打磨再打磨,瑞昱在原有的优势基础上,又新推一款更具性价比的USB3.0 Hub 主控IC,RTS5411-GR。此款IC的推出目的就是优化功耗,提高性能,降低客户Bom成本。那么,此款主控到底有何改善和更新呢?   众所周知,目前世面上的Hub 主控,诸如创唯(GL3520)  威盛(VL812) 等等,都需要外挂一颗Flash,把配置文件(Bin文件)烧录其中,才能控制各个下行端口的设置。 而且,还需要一颗降压IC(5.5~3V to 1.2V)。 如此才能是整块板子正常工作,达到设计要求。  而现在,RTS5411-GR内置Efuse功能,可把Bin程序烧录到IC内部,这样就省去外挂SPI FLASH,使客户再次Cost down.  另外,该IC已内置降压IC(5.5~3V to 1.2V) 因此,在整个Bom设计中,无需再加一颗降压IC。  上述两点,可以让整个Bom节省大约RMB1.00的成本,这使得客户的Hub产品更具价格优势!

  • 高级PID控制算法.

    Simulation can provide a lot of information about what the system is doing. We canadd the effect of different element, like Encoder resolution, ADC sampling rate, etc and understand how does it affect the system. Another benefit is the possibility to slow down the process, to gain insight on what happens of fast systems or, vice versa, speed up slow process.Because National Instruments is a unique company in the fact the we provide a fullhardware solution couple with a full development platform, we can use this tools in very particular ways For example, it is possible to combine the LabVIEW Control Design and Simulation Module along with the FPGA module to quickly prototype a controller. One of the main benefits of this approach is that there is no need to compile the FPGA code, which allows for a quick algorithm design turnaround and debugging.

  • saber学习心得

    一般调用元件的话,使用PartGallery的search功能都能找到相应的器件。注意MaST IOLAMS这里有两种不同语言描述的元件,一般不能同时在一张原理图中使用。在PartGallery中browse目录按照大的应用领域和市场领域划分。比喻Elctrical目录下包含一些电气行业相关的模型。1.翻转元件:选中该元件(可选多个),按R键,可实现90度翻转。按F键可实现180度翻转。2.电容或电感初始电压或电流值设置:在电容或电感元件的属性里有一项ic设置,默认未设置(undef),设置其为想要的值即可。3.Saber中,设置元件属性时,不能带任何单位符号,如电阻的“9,”电压的“V”时间的“S等,否则saber会报错。4.Saber中,仿真文件名不能和元件库中的元件同名,否则会报错。5.Saber中,原理图名称最好不要与路径名中有重复,否则会报错。6.原理图放大或缩小:按“page up或”“page down即可7.局部放大显示波形:直接拖动鼠标放大,或按“page up即可8.恢复波形显示原始大小:按“page down,”在右键菜单里点“zoom→tofi即可”9.按鼠标中键可拖动整个原理图包括波形显示图。
