I have a lot a devices that fail with voltage spikes. Each time the same component burns and I would like to fix them. The real problem is finding the name of the component, as I only know that the package is probably a sot457 , has written the numbers 209 and it's in a buck converter configuration.
The voltage input it's rated at 9v, 0.6A. The output voltage could be 5v or 3.3v. I tried finding the component in digikey and Mouser but had no luck finding the same pin out.
If anyone know a better way to find smd components or know a buck converter with the same pin out even if the package it's a little bit bigger or smaller I would be very happy.
