I have integrate LTC7860 EVB design (DC2392A) in my board to get my board working from 7V-34V.
I have noticed that when applying voltage grater then 12V the LTC7860 seems to get into fault protection mode with Vout drooping for ~19sec and then retry again (Vout = Vin for ~400ms and then drop again).
If I power up my board @ Vin <12V and only after increasing the input voltage to 34V the boards works fine..
Do you have any Idea what can be the reason?
