ISL95855 Features Compliant with IMVP8^TM, the ISL95855 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 (VR)
outputs. The VR A output can be configured for 3-, 2-or
1-phase operation. VR B is configurable for 2-or 1-phase
operation and VR C supports 1-phase operation. The address
options programmable for these three outputs allow for
maximum flexibility in support of the IMVP8^TM 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. • Support Intel serial data bus interface
• System input power monitor (PSYS) supported
