4+2 Multiphase PWM Regulator for Intel IMVP8™ Desktop CPUs

Compliant with Intel IMVP8™, the ISL95824 provides a

Features

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 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/I C interface with SVID conflict free

• Green hybrid digital R3™ modulator

- Excellent transient response

- Phase shedding with power state selection

- Diode emulation in single-phase for high light load

efficiency

• Dual output controller

- Voltage regulator A: 4-, 3-, 2- or 1-phase designs with two

+12V integrated gate drivers

Based on Intersil’s Robust Ripple Regulator R3™ Technology,

the R3™ 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.

- Voltage regulator B: 2- or 1-phase designs with one +12V

integrated gate driver

• 0.5% system accuracy over-temperature

• Supports multiple current sensing methods

- Lossless inductor DCR current sensing

- Precision resistor current sensing

The ISL95824 has several other key features. The controller

features three integrated +12V gate drivers with two drivers on

the VR B output. The controller supports either DCR current

sensing with a single NTC thermistor for DCR temperature

compensation or more precision through resistor current

sensing if desired. Both outputs feature remote voltage sense,

• Differential remote voltage sensing

• Resistor programmable address selection, I

switching frequency for both outputs

and

MAX

programmable I

, adjustable switching frequency, OC

• Adaptive body diode conduction time reduction

protection and single VR_READY power-good indicator.

Applications

• IMVP8™ compliant desktops
