Power controller for Intel VR processors

11 June 2008 Power Electronics / Power Management

International Rectifier has introduced the IR3502 XPhase control IC for Intel VR11.0 and VR11.1 processors.

The IR3502 provides overall system control and interfaces with any number of IR's XPhase ICs, each driving and monitoring a single phase. The device's key features include 0,5% overall system setpoint accuracy and daisy-chain digital phase timing for accurate phase interleaving without the need for external components. Combined with the IR3507 phase IC, the IR3502 and IR3507 chipset provides the power state indicator (PSI) capability to improve voltage regulator module (VRM) light load efficiency.

The IR3502 includes a host of protection features and a high level of programmability including programmable 250 kHz to 9 MHz clock oscillator frequency to provide per-phase switching frequency of 250 kHz to 1,5 MHz, programmable dynamic VID slew rate and programmable VID offset or no offset, in addition to high speed error amplifier with wide bandwidth of 30 MHz and fast slew rate of 10 V/μs. It also features improved droop capability that reduces the potential need for an external thermistor.
