Part Number: LM5085EVAL Other Parts Discussed in Thread: LM5085 Dear Sir:
In LM5085 datasheet,Vin MAX is 75v,But EVAL said Vin MAX is 60v,Is this contradictory?
Hi Privthi,
LM5085 seems good for this application, I ran a quick WEBENCH design for 48V-72Vin to 4V 2A out and the load transient seems good.
Your 47µH inductor saturates at 1.9A though, the inductor could saturate during your load transient to 2A. I…
Tadeusz,
You copied the LM5085EVAL design? Did you also copy the layout or see the layout example near the end of the datasheet?
If the designs are similar then the results should be similar.
Let me know,
