第一章开关电源设计的一般考虑 在设计开关电源之前，应当仔细研究要设计的电源技术要求。现以一个通信电源模块的例子来说 明设计要考虑的问题。该模块的技术规范如下(The first chapter is generally considered switching power supply design before switching power supply design, should carefully study the technical requirements to design power. Now with a communication power module design examples to illustrate the problem to be considered. Technical specifications of the module are as follows)
