Hello
We have buy a STEVAL-ISC004V1 the doc do not say the maximum voltage but by analizing the shematic i watch only the ST1S14PHR receive Vin then i think he can accepte 48V
But i have connect it to a 45V and i see D0 burn But no D0 on your shematic
I finaly found it on BOM is a QFN1610 ESDA25P35 (22V TSV)
In the BOM i watch C2 and C2' are also limited to 25V
I have test on 30V my board work. Can i use it with 48V (if i change C2 and C2' and remove D0?)
Why do you have limite to 22V?
