about the MAX supply current of the TX1

Now I use the TX1 module to design a product,but consider of some factors I can only use the adapter of 12V 2.5A;
the document shows that “VDD_IN Imax” is 3A and Power efficiency is higher when the input voltage is lower;Does it mean that the supply current comes to 3A when I use the 5.5V VDD input; Will “12V 2.5A” Meet the requirements of TX1 power supply?
thanks for answering my question.

The stable module power is about 6.5w ~ 15w, Imax 3A means the maximum current when power is maximum too, and yes the input voltage is minimum 5.5V. "12V 2.5A " is ok for module.

thank you for your answer.
