  • LM22678-Q1: Regulator immediately blows up

    Resolved
    Part Number: LM22678-Q1 I built a power supply following the schematic generated by webench, but it draws a very high current from source and blows up almost instantaneously when switched on. It must be something very obvious, but I can't see it at the…
