DRV8301: Buck Converter in DRV8301

Hi,

I am using TMS320F28069_Drv8301 kit. I wanted to use 5v o/p from DRV8301 in my custom pcb but I did not understand which pin gives output of buck converter (i.e 5volt).

Do I need to adjust internal buck converter in some way and get output from particular pin?

and it will be lot helpful if somebody can explain how buck converter is used in DRV8301_F28069 kit

Thanks,

Ayushi
