Power Management system: Power Supply Regulators
Embedding Power Management functions into SoCs targeting portable application: a new trend turning into a must
This trend is coupled with the stringent need to manage different voltage islets within a SoC for optimizing dynamic and static power consumption, giving the architectural choice of splitting into a logic IC at an advanced node from a mixed signal IC merging the functions of a Companion.
Virtual Components for power management should then solve an additional issue beyond the usual equation of being efficient and optimized to the driven load, namely being adapted to the noise constraints for a safe integration.
As the enabler of mixed-signal System-on-Chips, Dolphin’s Virtual Components for power-supply control are optimized in noise profile and Bill-of-Material to make integration straightforward.
