In reply to the discussion :https://ez.analog.com/power/f/q-a/109766/reason-for-lt8315-failure-along-with-output-capacitor
Inductor Voltage rating :400v
Switch current limit :270mA
Again IC failed with same burnt mark after replacing standard inductor with high voltage inductor.
So far, IC failed in 2 units.
What could be the reason for the failure.
Refer the Schematics attached in previous discussion referred above.
Suggest a suitable solution at the earliest which would be helpful for us.
What's the sensing resistor value on the failed boards? 0.4 Ohm (in the schematic) or 0.2 Ohm (in the picture)?
