其他书籍 Every day, patches are created to cover up security holes in software applications and operating sys
Every day, patches are created to cover up security holes in software applications and operating systems. But by the time you download a patch, it could be too late. A hacker may have already taken advantage of the hole and wreaked havoc on your system. This innovative book will help you stay one st ...
书籍 DSP in Power Electronics Control Circuits
The first edition of the book was one of the elements of my habilitation (a quali-
fication above a Ph.D., which is a necessary step for obtaining the title of a
professor in Poland and other European countries), and as a result it was subse-
quently very carefully reviewed by four reviewers. The ha ...

电源技术 低电压FPGA的高性能开关电源解决方案
 
The core voltages for FPGAs are moving lower as a resultof advances in the fabrication process. The newest FPGAfamily from Altera, the Stratix® II, now requires a corevoltage of 1.2V and the Stratix, Stratix GX, HardCopy®Stratix and CycloneTM families require a core voltage of1.5V ...
电源技术 DN443 2.2V降压型同步控制器
 
Many telecommunications and computing applicationsneed high effi ciency step-down DC/DC converters thatcan operate from a very low input voltage. The highoutput power synchronous controller LT3740 is idealfor these applications, converting input supplies rangingfrom 2.2V to 22V to outputs ...
单片机编程 XL6003 300KHz 36V Boost 3W LED
The XL6003 regulator is fixed frequency PWM Boost (step-up) DC/DC converter, capable ofdriving 1050mA load current with excellent line and load regulation. The regulator is simple to use because it includes internal frequency compensation and a fixed-frequency oscillator so that it requires a minimu ...
