Hello, I am in the final stage of replacing our current DCDC converter by MP9486AGN-Z. we have an input range of 7-60V (nominal 24V) and an output current of max. 1A @ 5V. I ordered some samples and assembled a test circuit on a breadboard pcb. R204 = 24k, R205 = 1k [Screenshot 2022-05-18 at 1…

Hi Oliver, Apologies for the delayed response. I think R205 should be 10k for 5V output. Should be a typo? For SCP recovery, I think the oscilloscope scale should be longer (~40ms/div). This can bee seen in the datasheet plots. Also, you can go through the attached document for 5V, 1A applicatio…

This IC is not very stable, I made a thread with no resolution here:

I finally abandoned it, using MAX17643 instead. Very stable and no more issues.
