100-15V TO 12V DCDC 原理圖 PCB BOM表

高的工作電壓高達(dá)100V N雙N溝道MOSFET同步驅(qū)動 The D810DCDC is a synchronous step-down switching regulator controller that can directly step-down voltages from up to 100V, making it ideal for telecom and automotive applications. The D810DCDC uses a constant on-time valley current control architecture to deliver very low duty cycles with accurate cycle-by-cycle current limit, without requiring a sense resistor. A precise internal reference provides 0.5% DC accuracy. A high bandwidth (25MHz) error amplifi er provides very fast line and load transient response. Large 1Ω gate drivers allow the D810DCDC to drive multiple MOSFETs for higher current applications. The operating frequency is selected by an external resistor and is compensated for variations in VIN and can also be synchronized to an external clock for switching-noise sensitive applications. Integrated bias control generates gate drive power from the input supply during start-up and when an output shortcircuit occurs, with the addition of a small external SOT23 MOSFET. When in regulation, power is derived from the output for higher effi ciency.

USB TO Gigabit LAN網(wǎng)卡的設(shè)計與制作

畢業(yè)設(shè)計 USB TO Gigabit LAN 網(wǎng)卡隨著網(wǎng)絡(luò)技術(shù)飛速發(fā)展，多媒體的應(yīng)用越來越多，人們對網(wǎng)絡(luò)的要求也越來越高，為了適應(yīng)市場的需求，網(wǎng)卡出現(xiàn)了。它以其結(jié)構(gòu)簡單、成本低廉、兼容性強(qiáng)等諸多的優(yōu)越性得到了廣泛的應(yīng)用。由于網(wǎng)絡(luò)的應(yīng)用越來越廣泛，網(wǎng)卡的應(yīng)用也越來越多、功能越來越強(qiáng)大。開始時由于技術(shù)方面的限制，網(wǎng)卡只有10Mbps的吞吐量，由于網(wǎng)絡(luò)技術(shù)的發(fā)展，100Mbps吞吐量的網(wǎng)卡開始在市場上得到廣泛的應(yīng)用。而現(xiàn)在1000Mbps吞吐量的網(wǎng)卡的出現(xiàn)又給網(wǎng)絡(luò)的傳輸帶來了新的活力。論文中主要闡述了基于以太網(wǎng)的USB TO Gigabit LAN網(wǎng)卡的設(shè)計與制作。論文首先對以太網(wǎng)進(jìn)行了介紹，緊接著講了網(wǎng)卡的基本知識。隨后又對USB TO Gigabit LAN網(wǎng)卡的電路設(shè)計和制作進(jìn)行了詳細(xì)的描述。論文還包括了USB TO Gigabit LAN網(wǎng)卡的調(diào)試等內(nèi)容。

FREESCALE單片機(jī)的C編程教程

1.The C Programming Language is a powerful, flexible andpotentially portable high-level programming language. 2.The C language may be used successfully to create a programfor an 8-bit MCU, but to produce the most efficient machinecode, the programmer must carefully construct the C Languageprogram.3.The programmer must not only create an efficient high leveldesign, but also pay attention to the detailed implementation.

PCA9541 2 to 1 I2C-bus master

The PCA9541 is a 2-to-1 I2C-bus master selector designed for high reliability dual masterI2C-bus applications where system operation is required, even when one master fails orthe controller card is removed for maintenance. The two masters (for example, primaryand back-up) are located on separate I2C-buses that connect to the same downstreamI2C-bus slave devices. I2C-bus commands are sent by either I2C-bus master and are usedto select one master at a time. Either master at any time can gain control of the slavedevices if the other master is disabled or removed from the system. The failed master isisolated from the system and will not affect communication between the on-line masterand the slave devices on the downstream I2C-bus.

3-V TO 5.5-V MULTICHANNEL RS-2

The MAX3243E device consists of three line drivers, five line receivers, and a dual charge-pump circuit with±15-kV ESD (HBM and IEC61000-4-2, Air-Gap Discharge) and ±8-kV ESD (IEC61000-4-2, Contact Discharge)protection on serial-port connection pins. The device meets the requirements of TIA/EIA-232-F and provides theelectrical interface between an asynchronous communication controller and the serial-port connector. Thiscombination of drivers and receivers matches that needed for the typical serial port used in an IBM PC/AT, orcompatible. The charge pump and four small external capacitors allow operation from a single 3-V to 5.5-Vsupply. In addition, the device includes an always-active noninverting output (ROUT2B), which allowsapplications using the ring indicator to transmit data while the device is powered down. The device operates atdata signaling rates up to 250 kbit/s and a maximum of 30-V/ms driver output slew rate.
