Can LTM4653 be used in Constant Current mode?

Hi,

I'm interested is there a way to use LTM4653 in constant curren mode?  would need to convert unregulated 30-50VDC  to current regulated  0..4A with Vout Max 5V.

LTM4653 seems to be ideal except it has no current limit  or CC regulation pin. Wandering is there any way to use it such mode?
