Claim 0:
1. A stimulation therapy method using an implantable medical device (IMD), the IMD including a battery and a lead system comprising one or more leads configured to be positioned proximate to a patient's tissue, wherein each lead includes a plurality of electrodes, the method comprising:
providing a first voltage multiplier configured to generate a range of target voltages at an output node based on a voltage supplied by the battery;
providing a plurality of stimulation engines (SE), each SE respectively including: a second voltage multiplier that is coupled to the output node of the first voltage multiplier and that is operative to drive an anodic node; and a current regulator that is powered by a floating power supply and that is coupled to a cathodic node;
selectively coupling a select portion of the electrodes of the lead system to a corresponding number of SEs at respective anodic and cathodic nodes according to a stimulation set; and
applying stimulation therapy to the patient's tissue according to the stimulation set.
