Other Parts Discussed in Thread: LM5148
Tool/software:
I'm using the LM5148 and noticed that even though I’ve pulled the PFM pin to AGND (to force CCM mode), the converter still appears to operate in DCM (discontinuous conduction mode) at transient load.
Additionally, during soft start, I don’t observe any PWM switching activity — the MOSFET gate remains low, and the SW node stays constant near the 15V voltage .
