Rev 0.00
May 4, 2016 1+2+1 Voltage Regulator for Intel IMVP8в„ў CPUs Features Compliant with Intel IMVP8в„ў, the ISL95857A 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. 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 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. Supports Intel serial data bus interface
-PS4 Power Domain entry/exit fully supported System input power monitor (PSYS) supported Three output controller
-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 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
transients and improved light-load efficiency due to diode
emulation mode with load-dependent low switching frequency. Low supply current in PS4 state Supports multiple current sensing methods …
