International Rectifier’s Xphase family has been expanded to include the IR3500 Control IC and IR3505 Phase IC. This chipset provides a complete Intel or AMD CPU power solution while reducing external the parts count. With simple six-bit voltage programming, the IR3500 is easily configured for use in general purpose, multiphase applications.
Specifically, the XPhase chipset features programmable dynamic voltage identification (VID) slew rate, programmable VID offset and load-line output impedance, hiccup over-current protection with delay to prevent false triggering, and a simplified power-good output to indicate correct operation and prevent false triggering. Pricing is $1.95 each for the IR3500MPBF and IR3500MTRPBF, and $1.65 each for the IR3505MPBF and IR3505MTRPBF.
