[1] Even if nominal maximum current is 1A, '''actual current availability may be limited by the current sourcing capability (2A) of the DC/DC feeding PF3000 PMIC'''. System integrator has to assess load balancing carefully, depending based on the overall configuration of the entire application's configuration(USB loads, processor computation, WiFi/Bluetooth module etc.).
[2] AUX_5V is generated by a 600mA boost DC/DC converter. As this converter powers USB devices connected to J47 and J48 - if any - and DWM WiFi/Bluetooth module (if populated), maximum current available at connector J54 can not be provided.
