Dedicated DC supply should be connected to VDDC or VDDA for DC application?

Hi,


Are there any internal charge pump or bootstrap circuit in LT4322?


If not, in order to keep the MOSFET constantly on for 100% duty cycle, we have to generate dedicated DC supply and connect it to either VDDC or VDDA, right?
