摘要
非同步DC/DC芯片拥有超高的工作效率和很大的带载能力,在汽车电子零部件使用率越来越广泛。针对不同的工作电流,其工作模式会发生可能会变化,会产生较大的电源纹波,引起EMC问题。而汽车电子现在对EMC的标准越来越严格,故首先要把开关电源的引起的EMC问题解决。文章主要是介绍开关电源芯片使用,及芯片外围器件的选型,并结合芯片LV13603A作详细的介绍。
The asynchronous DC/DC chip has ultra-high working efficiency and great carrying capacity, so it uses more and more extensive in automobile electronic components. According to different working currents, their working modes may change, resulting in larger power ripple and emc. This paper mainly introduces the use of switching power supply and the selection of peripheral devices of the chip, and makes a detailed introduction in combination with the chip LV13603A.
