TPS564247: High Quiecent Current with no load

Part Number: TPS564247
Other Parts Discussed in Thread: TPS564242


I am now designing a new power supply for a new pcb, 

i used TPS564247 for the main voltage converison from 12V to 5 V.

my design is attached, for some reason there is high quiecent current with no load connected - about 9-12 mA.

from what i read in teh Technical sheets it suppose to be in the ten's or hundred's uA

can someone figure out what is wrong here?
