Other Parts Discussed in Thread: LM25088
I would like to know the function of Rramp resistor in the below configuration. Datasheet recommends Rramp ony for VOUT>5V but my VOUT is 5V. And also why a 1M ohm resistor is used.

Hi
Ramp is provide extra proper slope compensation for LM25088. I suggest you can leave it open if no issue when the circuit work. but if you found some unstable condition, you can try to assembly this resistor to see any improvement for stability.
Thanks
Hi
1M ohm can privde around 7.8uA extra slope compensatin(internal is 25uA) connect to Vin will make the sloep compensation current too large.
Thanks
