LM2840: LM2840 short circuit protection? Vin = Vout after shorted output to ground

Part Number: LM2840

Hello,

we use the lm2840 in our design. i try the short circuit protection.

i connect the output from the lm2840 (after the inductor) to ground for just a second.

the device is after that damaged and the vout voltage = vin voltage.

i think the integrated FET is shorted.

the regulator isnt working anymore.

thanks for the answer

greetings

We use the following parts:
