Output capacitors on the MMPF0100NPAZES

[electricar]

Hello,

is it allowed to replace the recommended 2x22uF and 4x22uF output capacitors from the attached screenshot with 1x47uF and 2x47uF?

Could this lead to instability of the buck converters due to the higher ESR when paralleling less MLCCs? I couldn't find any useful information about the internal compensation on this topic.

The desired replacement capacitor is this one:

Thank you very much in advance.

Kind regards

Hello electricar ,

  if 47uF-capacitor is GCJ32ER70J476KE01, no problem. you can replace 2x22uF an 4x22uF with 1x47 and 2x47uF.
