TPS2660: fast trip recovery time (max spec) available?

Part Number:TPS2660

Hi,

My customer would need to know the maximum recovery time after fastrip got triggered. The datasheet just mentions a few usec and figure 44 indicates 200µs typical recovery time.
a) Is there a maximum spec for t_rec (see picture below)?  
b) Do you know any tricks/workarounds to minimize t_rec?

Thanks & best regards,
KF
