To request the full datasheet, please visit www.intersil.com/products/isl95855b 3+2+1 Voltage Regulator for IMVP8 Desktop CPUs with
Non-SVID VccSA Support
ISL95855B Features Compliant with IMVP8, the ISL95855B 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
programmable address options 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. VR C is a fixed non-SVID rail for VccSA in
support of desktop CPUs. Supports Intel serial data bus interface and programmable
SVID addresses for each output
