    anyone point me in the direction of a circuit to take the 5V from USB port
    and boost to 5.4V. My mobile phone requires 5.4v to charge properly.

    thanks

    Not a circuit - a ~$7.00 complete product.
    You didn't say which brand cellphone - the above
    site has chargers for several brands.
