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.
