搞嵌入式的工程师们往往把单片机、ARM、DSP、FPGA搞的得心应手，而一旦进行系统设计，到了给电源系统供电，虽然也能让其精心设计的程序运行起来，但对于新手来说，有时可能效率低下，往往还有供电电流不足或过大引起这样那样的问题，本文十大金律轻松搞定DCDC电源转换电路设计。第一条、搞懂DC/DC电源怎么回事　DC-DC电源模块电路又称为DC/DC转换电路，其主要功能就是进行输入输出电压转换。一般我们把输入电源电压在72V以内的电压变换过程称为DC/DC转换。常见的电源主要分为车载与通讯系列和通用工业与消费系列，前者的使用的电压一般为48V、36V、24V等，后者使用的电源电压一般在24V以下。不同应用领域规律不同，如PC中常用的是12V、5V、3.3V，模拟电路电源常用5V 15V，数字电路常用3.3V等，现在的FPGA、DSP还用2V以下的电压，诸如1.8V、1.5V、1.2V等。在通信系统中也称二次电源，它是由一次电源或直流电池组提供一个直流输入电压，经DC/DC变换以后在输出端获一个或几个直流电压。
