USB2ANY: 3.3V Power supply

Part Number: USB2ANY

Hi Team,

I want to use USB2ANY for I2C and UART communication  to the MSP430. If I want to use an onboard 3.3V_ISO power supply(the USB2ANY's 3.3V power supply doesn't have enough current capability) to power MSP430, digital isolators and etc, can I connect 3.3V_ISO and it's ground to USB2ANY's 3.3VEXT and GND? Thanks.

Best regards,

Penny
