January 29, 2015 Single-Phase Core Controller for VR12.6 Features The ISL95813 single-phase controller provides a fully
compliant VR12.6 power supply solution for Intelв„ў
microprocessors. It provides a tightly regulated output voltage
that is programmed through a high speed serial bus interface
with the CPU. This interface also allows the CPU to acquire
real-time information from the voltage regulator (VR), which
includes load current and VR temperature. Full VR12.6 specification compliance Wide input voltage range: 4.6V to 25V R3в„ў control architecture delivers excellent transient
response and power state mode transitions Current monitor (IMON) with temperature compensation Based on Intersil's Robust Ripple Regulator R3в„ў Technology,
the PWM modulator provides faster transient response and
settling time when compared against traditional modulation
schemes. Its variable frequency topology also allows for
natural period stretching Discontinuous Conduction Mode
(DCM) for increased efficiency and power savings in light load
situations. VRHOT# indicator for CPU protection Digitally selectable switching frequency:
-425kHz, 550kHz, 700kHz with ECO and PRO options Enhanced light-load efficiency discontinuous conduction
mode operation The ISL95813 has several other key features that include: DCR
current sensing with single NTC thermal compensation;
discrete resistor current sensing; differential remote voltage
feedback; and user-programmable boot voltage, IMAX, TMAX,
voltage transition slew rate and switching frequency.
