Single Phase Core Controller for VR12.6
ISL95813
The ISL95813 single-phase controller provides a fully compliant
VR12.6 power supply solution for Intel™ 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.
Based on Intersil's Robust Ripple Regulator (R3™) 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.
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.
Features
• Full VR12.6 specification compliance
• Wide input voltage range: 4.6V to 25V
• R3™ control architecture delivers excellent transient response
and power state mode transitions
• Current monitor (IMON) with temperature compensation
• 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
• Ultra-small 20 lead 3mmx4mm QFN package
• Enable and power-good monitor
Applications
• Notebook Computers
• Tablets, Ultrabooks™, and AIO
