Hi,
As the title states, our LM25011 burns when we apply 28V or more to it almost every time. If we connect 12V from the beginning and ramp up the voltage there is no problem ramping the voltage over 30V. After reading some posts here on the forum I think the voltage on Vin spikes and that is what's causing the burn.
I have attached our schematic and layout, we are a bit space constrained here, so any tips/advice on how to fix this by adding or moving on some components would be greatly appreciated.
Thanks.
