LMS3655: BIAS-pin

Part Number: LMS3655

Hi team,

My customer is considering to use the LMS3655. 

The 9.2.1.2.4 BIAS in the d/s describes that "Because this input is connected directly to the output, it must be protected from negative voltage transients. Such transients may occur when the output is shorted at the end of a long PCB trace or cable".   I believe that the negative voltage transients are caused by inductance of long PCB trace or cable and output capacitors(LC resonance). Is my understanding correct? 

Also, is there an equation to calculate the current out of the BIAS pin during negative voltage transients?

Regards,

Yamaguchi
