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

2011年，Realtek(瑞昱)開發出了業界公認的低功耗，高性能的USB3.0 Hub 主控，RTS5401-GR。它超小的體積(QFN76)和規范化的設計(USB IF認證，BC1.2和支持蘋果設備快充)，贏得了行內一致認可。如今，打磨再打磨，瑞昱在原有的優勢基礎上，又新推一款更具性價比的USB3.0 Hub 主控IC，RTS5411-GR。此款IC的推出目的就是優化功耗，提高性能，降低客戶Bom成本。那么，此款主控到底有何改善和更新呢？ 眾所周知，目前世面上的Hub 主控，諸如創唯(GL3520) 威盛(VL812) 等等，都需要外掛一顆Flash，把配置文件(Bin文件)燒錄其中，才能控制各個下行端口的設置。 而且，還需要一顆降壓IC(5.5~3V to 1.2V)。 如此才能是整塊板子正常工作，達到設計要求。 而現在，RTS5411-GR內置Efuse功能，可把Bin程序燒錄到IC內部，這樣就省去外掛SPI FLASH，使客戶再次Cost Down. 另外，該IC已內置降壓IC(5.5~3V to 1.2V) 因此，在整個Bom設計中，無需再加一顆降壓IC。 上述兩點，可以讓整個Bom節省大約RMB1.00的成本，這使得客戶的Hub產品更具價格優勢！

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.
