Dear Forum Members,
When the high side Mosfet gets shorted, the 19v power easily enters the CPU or PCH without any protection.
I think the buck-converter circuits in laptops should be modified somehow to protect the SOC against 19v when the high side Mosfet gets shorted.
How can we do that?
Can we put a safe isolation between the buck converter circuit and the SOC so that no failure in the buck converter circuit damages the SOC?
Thanks
note: The solution will be useful for both repairmen and manufacturers.
