Extensively rewritten to present the C++11 language, standard library, and key design techniques as an integrated whole, Stroustrup thoroughly addresses changes that make C++11 feel like a whole new language, offering definitive guidance for leveraging its improvements in performance, reliability, and clarity. C++ programmers around the world recognize Bjarne Stoustrup as the go-to expert for the absolutely authoritative and exceptionally useful information they need to write outstanding C++ programs. Now, as C++11 compilers arrive and development organizations migrate to the new standard, they know exactly where to turn once more: Stoustrup's C++ Programming Language, Fourth Edition.Bjarne Stroustrup是C++的设计师和最早的实现者，也是《C++程序设计语言》、《带标注的C++参考手册》和《C++语言的设计与演化》的作者。他从丹麦Aarhus大学和英国牛津大学毕业，现在是AT&T大规模程序设计研究部的负责人，AT&T特别成员，AT&T贝尔实验室特别成员，以及ACM特别成员。Stroustrup的研究兴趣包括分布式系统、操作系统、模拟、设计和程序设计。他也是Addison·Wesley的C++In-Depth系列书籍的编辑。

PW2330 develops a high efficiency synchronous step down DC-DC converter capable of delivering3A output current. PW2330 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. PW2330 adopts the proprietary instant PWM architecture to achieve fast transient responsesfor high step down applications and high efficiency at light loads. In addition, it operates atpseudo-constant frequency of 500kHz under continuous conduction mode to minimize the size ofinductor and capacitor
