对于开关电源输出可调的BUCK电路，反馈端都有分压电阻，用于采集输出端电压。本文就针对该分压网络,结合圣邦微的DCDC电源芯片 SGM6130的外围电路，对开关电源 BUCK电路的分压电阻行简单介绍。

反馈电阻的取值分两种情况：

第一种，如果电源转换芯片应用于高电流、无低功耗要求的情况，两个电阻的取值为几十KΩ，如果大于几百K欧姆，则电源转换芯片可能会变得不稳定或出现故障（因为反馈电路阻抗增加、FB引脚的寄生电容增大，会引入噪声）；如果小于几KΩ，则反馈电路的无功电流将会增加，电源转换芯片的效率就会降低。如图1所示，SGM6130的FB分压电阻R1和R2的取值为33K和10.5K，可以起到提高效率和稳定性的作用。

图1 SGM6130典型应用的电路示意图

第二种，如果电源转换芯片应用于有低功耗要求的情况，反馈电阻取值为几百KΩ，这样就可以减小反馈电路上的无功电流损耗，提高电源转换芯片的效率。

一般情况下，流过R1和R2的电流应该至少大于100倍流入FB引脚的电流。一般手册会给出流入FB引脚的电流的参数，有的手册会直接给出流过R1和R2的电流参数，有的手册会直接给出R2的范围。如图2所示，SGM6130直接给出了R2的参数典型值为10K。

图2 SGM6130分压电路R1和R2的计算公式

最后需要注意的是，开关电源芯片为了提高主控回路的频率响应，在R1上会并联一个前馈电容。

【经验】PFM模式对SGM6033 DCDC降压电源芯片的输出纹波有影响吗？

SGM6032/SGM6033是圣邦微推出的高性价比DCDC降压电源方案，电压输入范围2.5-5.5V，输出电压可调，主频4.6Mhz，负载能力1A，SGM6032/3具有低功耗模式，当电流较小的时候，会转为PFM模式下工作，对于市面上部分电源芯片来说，PFM模式意味着纹波系数大，本文通过实际测试，来了解SGM6033的PFM模式。
