TPS563208: No-load current is too large

Part Number: TPS563208
Hi TI:
We are debugging TPS563208, we found that the current consumption is about 20mA without load.
After the inductor is changed from the recommended 2.2uH to 3.3uH, the no-load current is 9.5mA. Why is the no-load current so large? ? ?
Is this normal with this part?
input 7.6V ,  output 3.3V
Can you test the TI‘s TPS563208 development board, what is the current consumption without the load???
