These plots show the transition between the two output voltages using the current injection method. As can be seen, this approach produces much smoother transitions. Any control voltage that can drive resistive loads can be used for this scheme, as opposed to the MOSFET switching approach, which can only be used with control signal sources that can drive capacitive loads. Additionally, this approach can be scaled to any output voltage combination and output load current. Thus, DSP power dissipation can be reduced by scaling the core voltage as needed.
