Hi,
Good day,
I am using LM3478 in buck boost config where my input range will be 10-15V and my output will be 12V and 3.5Amps max. In my current implementation the mosfet is heating up and fail's after few minutes and also there is a drop in the voltage when the input is 10.5V and output drops to 9V at 7Ohms of load. I have attached the schematic for your reference.
R52 is 8mOhms and J5 will be closed and my C42,C43 are 22uF tantalum capacitor with 30mOhms esr
Thanks in advance,
Regards,
