Evolution of power supply toward PSOC
If the power supply on chip (PSOC) concept is to be realised then the technology for the passive component fabrication must be compatible with integration on to the silicon IC. Already a high degree of integration can be achieved for the active parts of the converter, with the power switches, drivers and control integrated on to a single IC. The micro-inductor technology been developed at Tyndall can facilitate the integration of the magnetic components. The image below shows a 20 Mhz converter IC and a Tyndall fabricated micro-inductor.
