Product Overview

ISL95857AHRTZ-T is a ISL95857A 1+2+1 voltage regulator for Intel IMVP8™ CPUs. It provides a complete power solution for Intel microprocessors supporting core, graphics and system agent rails. The controller provides control and protection for three Voltage Regulator outputs. VR A and VR C outputs support 1-phase operation only, while VR B is configurable for 2- or 1-phase operation. The address options programmable for these three outputs allow for maximum flexibility in support of the IMVP8™ CPU. All three VRs share a common serial control bus to communicate with the CPU and achieve lower cost and smaller board area compared with a two-chip approach. Based on Intersil's Robust Ripple Regulator technology, the R3™ modulator has many advantages compared to traditional modulators. Application includes IMVP8 compliant notebooks, desktops, ultrabooks and tablets.
  • Supports intel serial data bus interface, PS4 power domain entry/exit fully supported
  • System input power monitor (PSYS) supported
  • VR A supports 1-phase VR design, VR B configurable for 2-, 1-phase VR design
  • VR C supports 1-phase VR design, 0.5% system accuracy over temperature
  • Low supply current in PS4 state
  • Lossless inductor DCR current sensing, precision resistor current sensing
  • Differential remote voltage sensing, programmable SVID address
  • Resistor programmable address selection, IMAX and switching frequency
