PowerSage

Intelligent power management integrated circuits that monitor an entire system and distribute power only when needed using autonomous dynamic voltage scaling.

PSG241x Series

The PSG241x series are highly integrated power management ICs with ultra-low dropout voltage regulators designed to supply VDDQ to DDR memory. A programmable interface for monitoring memory activity, coupled with an advanced On-Demand Power® algorithm, enable the regulated output voltage of the integrated regulator to be adaptively scaled in correlation with actual demand. The real-time tracking of supply voltage to memory activity enables maximum system power savings by minimizing the power spent on maintaining worst-case headroom in the power distribution network.
