开关稳压器的高效率特性，使其在越来越多的领域逐渐替代线性稳压器（LDO）。但由于电源的开关特性，使得不少工程师有开关电源纹波大的印象，所以在很多对纹波噪声比较敏感的系统中只考虑LDO。而实际上现在很多高性能的开关稳压器已经可以实现很小的纹波。本文艾诺半导体主要讲开关稳压电源输出电源纹波产生的原因和优化方法开关电源纹波产生的原因。

开关电源纹波产生的原因

开关电源输出的是直流电，但电感的电流并非纯直流，而是附加了三角波形状的纹波电流，纹波电流通过输出电容滤波。纹波电流在输出电容上产生纹波电压。输出电压纹波与输出阻抗、电感电流相关。

输出电容并非理想电容，存在寄生参数，可分解为等效寄生电感（ESL），等效寄生电阻（ESR），电容（C）的串联电路，电感纹波电流流过输出电容时，会在ESL，ESR和C上分别产生不同的电压纹波。

不同类型的输出电容，寄生参数的大小不同，三部分纹波所占的比例也有所不同。因此，使用不同类型的输出电容会得到不同波形的电压纹波。如上图所示，电解电容的ESR较大，纹波由ESR主导，波形与电感电流纹波形状类似。Tantalum电容和OSCON电容三者的影响都体现在纹波中。陶瓷电容的ESR和ESL都很小，主要由电容的充放电主导纹波类似电容的充放电曲线。

除了开关频率的纹波，我们测试时也会观察到高频的噪声，这有可能是测试的原因，但排除测试方法问题我们有时候依然能测量到该信号。这是由开关产生的高频噪声通过电感的寄生电容传输到了输出端。

（V_IN=40V, V_OUT=5V, I_OUT=3A, Fs=2MHz, BWL=200MHz）

电路参数相同，输出开关频率的纹波电压大小相同，但由于开关振铃的不同，使得在输出端产生的高频噪声不同。如果开关波形没优化好，高频噪声的幅值会远大于开关频次的纹波。优化开关波形，可以降低输出端高频的噪声，与此同时电路也会获得更好的EMI结果。

开关电源纹波的优化方法

由前面的分析可知，我们可以分别针对输出阻抗和电感电流来优化开关稳压器的输出纹波：

1.选择合适的输出电容，要使输出电压纹波最小，输出电容应当选更大的容量，更小的ESR和ESL，在高频电路中，叠层片式陶瓷电容不失为一个好的选择。

2.降低电感纹波电流，电感纹波电流可以通过提高工作频率，提高电感感量降低。而对于更高频率的噪声，我们可以选择寄生电容小的电感或者在输出端增加LC线路滤波。在不增加额外电路的情况下，我们也可以优化开关波形，降低震荡，减少高频噪声的产生。

艾诺半导体公司丰富系列的电源管理产品，如ES5423/ES5426/ES5415系列产品，具有低输出纹波、低静态电流、高频高效率、低EMI噪声、高功率密度、高可靠性等特点，并支持外部时钟同步功能。可以通过提高工作频率和多相并联来降低开关频次的纹波，同时低开关振铃的特性也实现了更低的高频纹波噪声和EMI噪声。
