某客户设计一款冰柜温控器，因为空间有限并没有采用传统搭配适配器输出5V/2A供电方案，新设计方案采用设计板载电源方式，在温控器前级输入端应用必易微电子的电源管理芯片 KP23132M+KP41240同步整流实现，在实际测试中发现高频纹波较大，影响到后面二级电源的正常工作，因为输入纹波过大，导致后级电路输出不稳定。客户AC-DC部分应用电路如下：

整改电路设计正常，但是在实际测试输出高频纹波时（44KHz）发现纹波较大，严重超过设计标准。实际波形如下：

从图中可以看到在43Khz情况下，纹波已经无法抑制。

一般来说高频纹波噪声来源于高频功率开关变换电路，在电路中，通过功率器件对输入直流电压进行高频开关变换而后整流滤波再实现稳压输出的，在其输出端含有与开关工作频率相同频率的高频纹波。

针对高频纹波我们主要从以下3个方面去考虑：

1、提高开关电源工作频率，以提高高频纹波频率，有利于抑制输出高频纹波。

2、加大输出高频滤波器，可以抑制输出高频纹波。

3、采用多级滤波

因为KP23132M无法通过RC调整频率，后来建议客户增加多级滤波方式，目前只有一颗输出电容，客户增加一级LC滤波之后效果有明显改善。

虽然相对来说成本有所增加，但是可以保证系统稳定的工作，我们在设计开关电源电路时在抑制纹波时一定要注意高频纹波对电路的影响。
