*Max current only available while battery powering.
Currently, to be compliant with the USB2 max current, only 500mA is available from an external power supply (MCU Power included).

Max Buck-Boost output current :

• TPS63070 : 2A in Buck or Boost mode.
• TPS63060 : 2A in Buck mode, 1.3A in boost mode.
