About ADP5054 Power Consumption

  ADP5054 is currently being used, and the required voltage level has been adjusted and normal working, but there are some very serious problems.
  The static power consumption of AD5054 is very high, as high as 1.2w (12V input, current 0.1a) without access to load.
I want to ask whether the chip itself is very high power consumption, or design problem, the following attached schematic diagram.
  According to ADIPOW, the design tool recommended by ADI, the switching frequency can only be set to 500KHZ, and I use the frequency of about 583KHZ.
  Thank you for your reply.
