LMR38015-Q1: Normal mode current is large than other buck DC/DC

Hello Team

     Using the LMR38015 5V fixed version, when the input voltage is 48V, the current is 14mA. There is no load on the 5V side, Fsw is 400KHz, L is 68μH, and the internal resistance is 1Ω. What is the reason for such a large power consumption of the Buck IC?
