Description

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.

Applications

  • LPDDR2 Memory Power Supplies
  • DDR4 (PSG2411A), DDR3, DDR3L, DDR3UL Memory Power Supplies
  • Mobile computers
  • Servers
  • Network switches and routers
