Desktop CPUs
ISL95856 Features Compliant with Intel IMVP8в„ў, the ISL95856 provides a
complete power solution for desktop microprocessors
supporting both the core (IA) and graphics (GT) rails. The
controller provides control and protection for one Voltage
Regulator (VR), which can be configured for 4-, 3-, 2-or
1-phase operation. The second VR is configurable for 3-, 2-or
1-phase operation. The VRs feature a programmable SVID
address to allow maximum flexibility in supporting desktop
processor SKUs. Both controller outputs 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 SMBus/PMBus/I2C interface with SVID conflict free Green hybrid digital R3в„ў modulator
-Excellent transient response
-Phase shedding with power state selection
-Diode emulation in single-phase for high light-load
efficiency 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. …
