INT-TPS61193-Q1 FB resister value

Hi Team,

 

I have customer in evaluation of TPS6193-Q1. One question that need your help. 

For the feedback resister divider, the spec recommends 130Kohm for bottom, thus the top could be around 600Kohm for customer panel used.

But OEM usually requires using less than 100Kohm resister for automotive.

Based on my understanding, the divider values could be lower, like 1/10 smaller, but at cost of higher leakage current through GND even when IC disabled, and could be tuned using feed-forward cap.

 

Could you help double check ? Any special request to use larger than 100K ohm for bottom resister ?

 

Thanks for your help.
