ISL95857AHRTZ-T

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.
