To request the full datasheet, please visit www.intersil.com/products/ISL95855A 3+2+1 Voltage Regulator for IMVP8в„ў CPUs
ISL95855A Features Compliant with IMVP8в„ў, the ISL95855A 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 IMVP8в„ў 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
-PS4 power domain entry/exit fully supported System input power monitor (PSYS) supported Three output controller
-VR A configurable for 3-, 2-, 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 Supports multiple current sensing methods
-Lossless inductor DCR current sensing
-Precision resistor current sensing Based on Intersil’s Robust Ripple Regulator (R3™) technology,
the R3в„ў modulator has many advantages compared to
traditional modulators. These include faster transient settling
time, variable switching frequency in response to load …
