Hello All,
I am designing power supply circuit for 24V truck system.
DC-DC convertor IC which i have selected is having continues input voltage maximum Vin_conti= 60V
& Absolute maximum input is of Vin_absolute = 70V.
There is a Load dump test in automitive i.e. 174V is applied for 350ms.
Also I need to pass another test of applying 48V for 10 minutes.
To pass this tests I have selected TVS Diode of 5000W with minmum breakdown voltage of 49V & maximum clamping voltage of 64V.
During the Load dump test TVS Diode will clamp to 64V which is greater by 4V than Vin_conti but less than
Vin_absolute ratings.
The question I am having is whether this extra 4V for few miliseconds will effect on DC-DC convertor or not?
kindly support me on this
best regards,
Nachiket
