VR11.1, 4-Phase PWM Controller with Phase Dropping, Droop Disabled and Load

Current Monitoring Features

The ISL6334D controls voltage regulator by driving up to 4

Features

interleaved synchronous-rectified buck channels in parallel. This

• Intel VR11.1 compliant with droop disabled

multiphase architecture results in multiplying channel ripple

frequency and reducing input and output ripple currents. Lower

ripple results in fewer components, lower cost, reduced power

dissipation and smaller implementation area.

• Proprietary Active Pulse Positioning (APP) and Adaptive

Phase Alignment (APA) modulation scheme

• Proprietary active phase adding and dropping for high

light-load efficiency

Microprocessor loads can generate load transients with

extremely fast edge rates and requires high efficiency at light

load. The ISL6334D utilizes Intersil’s proprietary Active Pulse

Positioning (APP), Adaptive Phase Alignment (APA)

modulation scheme, active phase adding and dropping to

achieve and maintain the extremely fast transient response

with fewer output capacitors and high efficiency from light to

full load.

• Precision multiphase core voltage regulation

- Differential remote voltage sensing

- ±0.5% closed-loop system accuracy over load, line and

temperature

- Bi-directional, adjustable reference-voltage offset

• Precision resistor or DCR differential current sensing

- Accurate channel-current balancing

The ISL6334D is designed to be completely compliant with

Intel VR11.1 specifications. It accurately reports the load

current via the IMON pin to the microprocessor, which sends

an active low PSI# signal to the controller at low power mode.

The controller then enters 1- or 2-phase operation with a diode

emulation option to reduce magnetic core and switching

losses, yielding high efficiency at light load. After the PSI#

signal is de-asserted, the dropped phase(s) are added back to

sustain heavy load transient response and efficiency.

- Accurate load current monitoring via the IMON pin

• Microprocessor voltage identification input

- Dynamic VID™ technology for VR11.1 requirement

- 8-Bit VID, VR11 compatible

• Average overcurrent protection and channel current limit

• Precision overcurrent protection on IMON pin

• Thermal monitoring and overvoltage protection

• Integrated programmable temperature compensation

• Integrated open sense line protection

The ISL6334D senses the output current continuously by utilizing

patented techniques to measure the voltage across the dedicated

current sense resistor or the DCR of the output inductor. Current

sensing circuits also provide the needed signals for

channel-current balancing, average overcurrent protection and

individual phase current limiting. An NTC thermistor’s

temperature is sensed via the TM pin and internally digitized for

thermal monitoring and for integrated thermal compensation of

the current sense elements.

• 1- to 4-phase operation, coupled inductor compatibility

• Adjustable switching frequency up to 1MHz per phase

• Package option

- QFN compliant to JEDEC PUB95 MO-220 QFN (Quad Flat

No Leads) package outline

A unity gain, differential amplifier is provided for remote voltage

sensing and completely eliminates any potential difference

between remote and local grounds. This improves regulation and

protection accuracy. The threshold-sensitive enable input is

available to accurately coordinate the start-up of the ISL6334D

with any other voltage rail. Dynamic VID™ technology allows

seamless on-the-fly VID changes. The offset pin allows accurate

voltage offset settings that are independent of VID setting.

• Pb-free (RoHS compliant)
