•Can I use VAUX to power additional circuits in my system?  How much current can VAUX supply without affecting the TPS61200 power supply performance.–

    The TPS61200 VAUX pin can supply up to 1mA of current to power additional external circuitry.  The VAUX voltage is an unregulated output between 2.4V and 5.5V. The voltage is internally switched to maintain the higher of the Vaux, Vin, Vout or SW node (L Pin) voltages.
