TPS4811-Q1: TPS1211/4811 pre-charge function

Part Number: TPS4811-Q1

Dear friends;

When my customer are evaluating TPS1211, they would like to know whether they can remove Q3 for pre-charge function on the bulk capacitor? Instead, could it by only using Q1 that could realize both pre-charge and current limit function at the start up?

 

Or do we have any other options could meet this current limitations while in precharge stage without adding additional FET?
