Application processors have increasingly difficult power management requirements as they control most phone functions including graphics processing, memory management and multimedia decoding. Power management consumes 20% of the phone’s PCB area, devouring critical real estate that battery or wireless band technology could enjoy. The need for more than 30 independent voltage rails is making power routing both difficult and area consuming, as well as impacting the integrity of the voltage signals during long, thin trace routing. This contributes to significant packaging and power filtering cost, and the requirement of power-wasting voltage guard-banding.
There is a better way. Design the SoC with Your Inner Power: Empower RIVRTMintegrated voltage regulators (IVR) eliminate wasted PCB space, spaghetti routing and poor power signal integrity. Achieve lower cost, smaller size, lower EMI, and very high system efficiency.
