通用的多電源總線,如VME、VXI 和PCI 總線,都可提供功率有限的3.3V、5V 和±12V(或±24V)電源,如果在這些系統中添加設備(如插卡等),則需要額外的3.3V或5V電源,這個電源通常由負載較輕的-12V電源提供。圖1 電路,將-12V 電壓升壓到15.3V(相對于-12V 電壓),進而得到3.3V 的電源電壓,輸出電流可達300mA。Q2 將3.3V 電壓轉換成適當的電壓(-10.75V)反饋給IC1 的FB 引腳,PWM 升壓控制器可提供1W 的輸出功率,轉換效率為83%。整個電路大約占6.25Cm2的線路板尺寸,適用于依靠臺式PC機電源供電,需要提供1W輸出功率的應用,這種應用中,由于-12V總線電壓限制在1.2W以內,因此需要保證高于83%的轉換效率。由于限流電阻(RSENSE)將峰值電流限制在120mA,N 溝道MOSFET(Q1)可選用廉價的邏輯電平驅動型場效應管,R1、R2 設置輸出電壓(3.3V 或5V)。IC1 平衡端(Pin5)的反饋電壓高于PGND引腳(Pin7)1.25V,因此:VFB = -12V + 1.25V = - 10.75V選擇電阻R1后,可確定:I2 = 1.25V / R1 = 1.25V / 12.1kΩ = 103μA可由下式確定R2:R2 = (VOUT - VBE)/ I2 =(3.3V - 0.7V)/ 103μA = 25.2 kΩ圖1 中,IC1 的開關頻率允許通過外部電阻設置,頻率范圍為100kHz 至500kHz,有利于RF、數據采集模塊等產品的設計。當選擇較高的開關頻率時,能夠保證較高的轉換效率,并可選用較小的電感和電容。為避免電流倒流,可在電路中增加一個與R1串聯的二極管。

The PL2303 USB to Serial adapter is your smart and convenient accessory forconnecting RS-232 serial devices to your USB-equipped Windows host computer. Itprovides a bridge connection with a standard DB 9-pin male serial port connector inone end and a standard Type-A USB plug connector on the other end. You simplyattach the serial device onto the serial port of the cable and plug the USB connectorinto your PC USB port. It allows a simple and easy way of adding serial connectionsto your PC without having to go thru inserting a serial card and traditional portconfiguration.This USB to Serial adapter is ideal for connecting modems, cellular phones, PDAs,digital cameras, card readers and other serial devices to your computer. It providesserial connections up to 1Mbps of data transfer rate. And since USB does not requireany IRQ resource, more devices can be attached to the system without the previoushassles of device and resource conflicts.Finally, the PL-2303 USB to Serial adapter is a fully USB Specification compliantdevice and therefore supports advanced power management such as suspend andresume operations as well as remote wakeup. The PL-2303 USB Serial cable adapteris designed to work on all Windows operating systems.

A Computer-On-Module, or COM, is a Module with all components necessary for a bootable host computer, packaged as a super component. A COM requires a Carrier Board to bring out I/O and to power up. COMs are used to build single board computer solutions and offer OEMs fast time-to-market with reduced development cost. Like integrated circuits, they provide OEMs with significant freedom in meeting form-fit-function requirements. For all these reasons the COM methodology has gained much popularity with OEMs in the embedded industry. COM Express® is an open industry standard for Computer-On-Modules. It is designed to be future proof and to provide a smooth transition path from legacy parallel interfaces to LVDS (Low Voltage Differential Signaling) interfaces. These include the PCI bus and parallel ATA on the one hand and PCI Express and Serial ATA on the other hand.
