Hi, I’ve just purchased the Drok 15A buck converter model 090413_EU from Amazon, since I don’t have an oscilloscope, could you please tell the max ripple with no load, full load, and 80-100W load?

Thank you very much for for your help.

Dear friend,
Thanks for your message.
Could you please tell us what input voltage output voltage is when it is no load, full load, and 80-100W load.
We need to know this parameters so that we can get the ripple.
Hope you can understand.
Have a nice day.
Best regards

Dear friend,
Thank you for your continued patience with us.
After testing, we found that the ripple is 400mV when it is no load, and it is 600mV when full load.
Hope this will help you.
Have a nice day.
Best regards

there is any other drok solution to achieve the same output-input voltage with a ripple less than 100mV?

Thank you

maybe the 090066_EU (rated 50mV ripple) models? this is a critical application so I cannot go over 120mV max ripple. Could you please test it with my input 19,7V and output 12V? Thank you very much for your help.

Since no reply received, have I to assume there aren’t drok products that can fulfill the maximum ripple of 120mV at 12V with a 6A load????

Hi Gerico,
Sorry for the late reply.
The ripple of 090066_EU will go over 120mV.
hope this will help you.
