TPS56339: TPS56339 caught fire

Shivananda Prasad

Part Number: TPS56339

Hello,

I used TPS56339 for one of my design for 24VDC to 5VDC conversion, upon testing it for 4 hours @ 1A load, I shorted the 5VDC terminals to test for the over current and TPS56339 caught fire.

Please let me know whether it is design problem or is it the issue with TPS56339 itself

I here with attaching the schematic file.

Hi,

Could you please share the schematic and layout? Let's review them.

And how did you short the output?
