【经验】降压电源芯片SGM6010的环路调试经验
圣邦微推出的降压电源芯片SGM6010,其输入电压范围为3V~5.5V,输出电压范围为0.8V~5V,该款DC-DC输出电流最大可达3A,适合低电压电源系统设计,可满足MCU或DSP的供电需求。对于SGM6010的电路的环路测试,将50欧姆电阻接入到输入端和采样电阻之间,在将50欧姆电阻的两端用双绞线连接到环路分析仪上。SGM6010的电路接线图如下:
图1:SGM6010的电源环路测试接线图
按照以上电路连接,参考闭环回路增益为0dB(无增益)的情况下,相位裕度是应大于45度的测试标准,测得SGM6010环路频响特性如下,可以看出在0dB时候,相位裕量不足45度,电源会有少量的减幅震荡。
图2:SGM6010频响特性(调试前)
通过分析调试,在COMP脚的对地增加一个560pF的电容,再次通过环路分析仪测试此电源的频响特性。
图3:调试后的SGM6010的电源环路测试接线图
图4: SGM6010频响特性(调试后)
通过以上调试,总结如下:
降压电源芯片应用于MCU供电中,5V转2.5V,若是在实际环路测试中,相位裕量不足,可以在SGM6010的COMP脚对地增加电容560pF,可以改善电源的高频特性,增加相位裕量,从而提高电源环路的稳定性。
