Part Number:LMR16030
请问输出电容能否使用22uF贴片电容+100nF贴片电容+220uF插件电解电容?
Can we use 22uF CHIP CAP+100nF CHIP CAP+220uF DIP E.CAP for the output capactitances of LMR16030?

1, In datasheet of LMR16030,the output capactitance is recommended as 2x47uF CHIP CAP or 1x100uF E.CAP.
规格书推荐是2个47uF贴片电容,或1个100uF的电解电容。
According to our actual ccmponents( inductor is 10uH 10%). Online design, the output capactitance is recommended as 2x68uF CHIP CAP or 2x82uF E.CAP.
实际用料上,我们公司常用的电感是10uH 10%, 以此在线设计得出的输出电容是2个68uF贴片电容,或2个68uF电解电容+ 2.2uF电容
2, 按实际公司常用的元件和成本控制,请问输出电容能否使用22uF贴片电容+100nF贴片电容+220uF插件电解电容?
According to our actual ccmponents and cost. Can we use the in the schematic diagram 22uF CHIP CAP+100nF CHIP CAP+220uF DIP E.CAP?
In the range 18~30VAC of the supply voltage of the product, when system on after power on 1second ,the output voltage 5V is normal and the ripple is small(purple waveform).
使用电子负载在18~30VAC范围内,带载0~2A的情况,输出电压5V正常, 纹波大概50mV或小于50mV(紫色波形)。
Electron Loading 0~2A, the output voltage 5V is normal and the ripple is about 50mV or less then 50mV(purple waveform).
18VAC
24VAC
30VAC

Hi
可以替代的,datasheet一般是推荐陶瓷电容,但是实际用电解电容加陶瓷电容并联也是可以的,主要就是注意容值大小,和并联后的ESR.
