I am debugging LT1912 switching step down DC-DC regulator.
I have checked schematic, PCB layout, part marking and soldering connections, they all looks fine.
But it is not working; the voltage at FB pin is only 0.09V instead of 0.79V, which is mentioned on datasheet.
Run/SS pin is powered with 3.6V.
What the problem with this simple LT1912?
Please help.
Thank you so much!!!
