Desktop CPUs
ISL95858 Features Compliant with Intel IMVP8в„ў, the ISL95858 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 3-, 2-or 1-phase
operation. The second VR is configurable for 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. Dual output controller …
