LMZ34002: IC Connections

Part Number: LMZ34002
I had a query regarding LMZ34002 IC which we have used in one of our projects. The datasheet does not specifically mention to short all the PH (Phase switch node) pins of the IC. Does the IC performance get affected if the pins are left floating?

    The PH pins are connected internal to the LMZ34002, so the device will operate as expected if the pins are not connected on the PCB. The copper connection of the PH pins will help with thermal performance, but as long as the PH pins and pads are soldered to pads on the PCB it will aid in thermal relief.
