Claim:
1. An implantable component of a hearing prosthesis, the implantable component comprising: an implant coil; a housing configured to be implanted in a recipient; a rechargeable energy source; a converter circuit configured to implement one or more speech processing or coding strategies; a stimulation decoder configured to provide an output to a hearing stimulator that is configured to deliver electrical stimulation signals to a recipient of the hearing prosthesis; and a single transformer having a primary side connected to both the implant coil and the rechargeable energy source such that power received at the implant coil is provided to the rechargeable energy source via the primary side of the single transformer, wherein the single transformer electrically isolates the implant coil from the stimulation decoder and the hearing stimulator, and wherein the single transformer modifies an output of the rechargeable energy source for use by the stimulation decoder and the hearing stimulator, and wherein the stimulation decoder is connected to a secondary side of the single transformer so as to receive signals generated by the converter circuit via the single transformer.
