1. An implantable infusion device comprising:

  • a voltage boost circuit configured to selectively generate an output voltage by boosting a first voltage provided by a battery, the voltage boost circuit including;

    a signal generation circuit configured to generate control signals, anda charge pump circuit configured to generate the output voltage in response to the control signals,wherein in response to a request for a predetermined voltage, the signal generation circuit is configured to;

    generate the control signals using a first profile for a first period of time, andgenerate the control signals using a second profile for a second period of time subsequent to the first period of time,wherein the charge pump circuit is configured to increase the output voltage to;

    an intermediate voltage less than the predetermined voltage in response to the first profile of the control signals, andthe predetermined voltage in response to the second profile of the control signals.
