Hello,
I have tried to follow the recommended circuit layout as closely as possible.
I am using the TPS56339DDCR buck converter in a custom circuit where circuit is design for 19V to 2.00V @ 4A with WEBENCH Power Designer. But i found the TPS56339DDCR would be damaged as well as input protection diode D1(D20V0L1B2WS-7) also burn out when DC power adapter(Vin=19V,Iout=4.47A) connect to the input(This happened without any load at Vout).An image of the circuit design is attached.Could you give some advice please? Please let me know as soon as possible if any solution found.
Thank You.
