The LTM4601 DC/DC μModule regulator is a completehigh power density stepdown regulator for up to 12Acontinuous (14A peak) loads. The device is housed ina small 15mm ¥ 15mm ¥ 2.8mm LGA surface mountpackage, thus the large power dissipation is a challengein some applications. This thermal application note willprovide guidelines for using the μModule regulator inambient environments with or without air fl ow. Loadcurrent derating curves are PROVIDED for several inputvoltages and output voltages versus ambient temperatureand air fl ow.

Abstract: This application note describes how to build, debug, and run applications on the on-board MAXQ622microcontroller to interface with the DS8005 dual smart card interface. This is demonstrated in both IAREmbedded Workbench and the Rowley CrossWorks IDE, using sample code PROVIDED with the kit.
提出了一種以S3C2440A為核心處理器的銀行評價器的設(shè)計方案，并結(jié)合XILINX公司的XL95144XL型CPLD，輔助S3C2440A，實現(xiàn)該銀行評價器的各部分功能以及系統(tǒng)信號之間的相互協(xié)調(diào)。該評價器在系統(tǒng)設(shè)計上采用液晶屏顯示，代替了以往簡單的數(shù)碼管電路的顯示模式，在視覺上給人以全新的享受。同時，評價器增加了新的網(wǎng)絡(luò)供電方式，只要將評價器連接上網(wǎng)絡(luò)就可以正常工作，方便了客戶的使用。總之，此款銀行評價器采用了嵌入式系統(tǒng)的設(shè)計方案，大大豐富了系統(tǒng)功能，實現(xiàn)一個銀行評價器設(shè)計的新突破。
Abstract: S3C2440A of SamSung company is the core component of the embedded system. A design of bank assessor based on S3C2440A was PROVIDED in this paper. It used XL95144XL combined with S3C2440A to realize all the functions and coordination with system signals. This bank assessor used LCD to display instead of the former simple digital display and PROVIDED a new seusuous enjoment. Meanwhile，it PROVIDED a new method of network power supply，that the bank assessor could regularly work once it connected to the network，which is convenient for customers to use. In a word，this assessor takes embedded system，enriches the system’s functions and reclizes a new breakout.

為解決傳統(tǒng)可視倒車雷達視頻字符疊加器結(jié)構(gòu)復(fù)雜，可靠性差，成本高昂等問題，在可視倒車雷達設(shè)計中采用視頻字符發(fā)生器芯片MAX7456。該芯片集成了所有用于產(chǎn)生用戶定義OSD，并將其插入視頻信號中所需的全部功能，僅需少量的外圍阻容元件即可正常工作。給出了以MAX7456為核心的可視倒車雷達的軟、硬件實現(xiàn)方案及設(shè)計實例。該方案具有電路結(jié)構(gòu)簡單、價格低廉、符合人體視覺習(xí)慣的特點。經(jīng)實際裝車測試，按該方案設(shè)計的可視倒車雷達視場清晰、提示字符醒目、工作可靠，可有效降低駕駛員倒車時的工作強度、減少倒車事故的發(fā)生。
Abstract:
A new video and text generation chip，MAX7456，was used in the design of video parking sensor in order to simplify system structure，improve reliability and reduce cost. This chip included all the necessary functions to generate user-defined OSDs and to add them into the video signals. It could be put into work with addition of just a small number of resistances and capacitors. This paper PROVIDED software and hardware implementation solutions and design example based on the chip. The system had the characteristics of simplicity in circuit structure，lower cost，and comfort for the nature of human vision. Loading road test demonstrates high video and text display quality and reliable performance，which makes the driver easy to see backward and reduces chance of accidents.
