Hi,


  I want to use the ADP5054 for Xinlinx Ultrascale K ,According to the ADP5054 SPEC,CH1&CH2 current output can up to 10A ,the CH3&CH4 up to 2.5A.


But  when adjust the load up to 6A,the CH1&CH2 efficiency drop to 58%. And when adjust the load up to 0.8A,the CH3&CH4 can not output the voltage , like get into the


overcurrent protection mode.


 Please help me check the schematic and How to slove the Problem?


My design refers to the ADP5054-EVALZ，and the BOM is same as the EVALZ, the schematic as follows.
