搞嵌入式的工程師們往往把單片機、ARM、DSP、FPGA搞的得心應(yīng)手，而一旦進行系統(tǒng)設(shè)計，到了給電源系統(tǒng)供電，雖然也能讓其精心設(shè)計的程序運行起來，但對于新手來說，有時可能效率低下，往往還有供電電流不足或過大引起這樣那樣的問題，本文十大金律輕松搞定DCDC電源轉(zhuǎn)換電路設(shè)計。第一條、搞懂DC/DC電源怎么回事　DC-DC電源模塊電路又稱為DC/DC轉(zhuǎn)換電路，其主要功能就是進行輸入輸出電壓轉(zhuǎn)換。一般我們把輸入電源電壓在72V以內(nèi)的電壓變換過程稱為DC/DC轉(zhuǎn)換。常見的電源主要分為車載與通訊系列和通用工業(yè)與消費系列，前者的使用的電壓一般為48V、36V、24V等，后者使用的電源電壓一般在24V以下。不同應(yīng)用領(lǐng)域規(guī)律不同，如PC中常用的是12V、5V、3.3V，模擬電路電源常用5V 15V，數(shù)字電路常用3.3V等，現(xiàn)在的FPGA、DSP還用2V以下的電壓，諸如1.8V、1.5V、1.2V等。在通信系統(tǒng)中也稱二次電源，它是由一次電源或直流電池組提供一個直流輸入電壓，經(jīng)DC/DC變換以后在輸出端獲一個或幾個直流電壓。
