International Rectifier, IR® (NYSE:IRF), a world leader in power management technology, introduced the IR3514 and IR3507 XPhase® chipset for AMD® parallel and serial VID (PVID and SVID) processors. The IR3514 control IC enables designers to migrate from AMD processors requiring a parallel VID to SVID processors without the need to change the motherboard. Combined with the IR3507 phase IC, the IR3514 provides Power Saving Interface (PSI) capability to turn phases(N-1) on or off depending on CPU load requirements. The IR3514 is designed to receive power savings commands through the SVI serial bus and communicates this information to the IR3507 phase IC to improve efficiency at light loads and MIPS per watt.
