LM22675: About Line reguration question of LM22675.

Part Number: LM22675

Dear support member,

My customer use LM22675.

I have a question about line reguration.

Daimen is a 3 phase power supply,
The input voltage fluctuates at intervals of 8 ms at 0.1 V.
The output voltage fluctuated at intervals of 8 ms at 50 mV.

Is this normal behavior of IC?
If it is not normal operation,would you teach me the reason?

Specification condition
Vin: 27 V
Vout: 5 V
Iout: 1A

Best regard.

Hi Bob,

I think we do not have a control on the input, as for the output voltage it seems sound reasonable.
Do you have a scope capture of the output voltage ripple?

Thanks

Dear Arief Hernadi,

Thank you very much for reply.

I check if there is a waveforme.
I will feedback it.

Best regard.
