Is that someone has already had this problem with the controller? (Which I replace LM2575S-5) that I had in stock, why this piece to explode?
with a big POWF .... However, this regulator supplies three components 74HC kind ..
I wonder if this can have a relationship with my non-armored cable or bad quality Components. i cannot read the original part number,because ic is completly destructed.

I will completely re-draw the circuit completely and add more protections, options, any suggestions?
