Multi-Output Controller with Integrated

MOSFET Drivers for AMD SVI Capable

Mobile CPUs

Features

• Core Configuration Flexibility

- Dual Plane, Single-Phase Controllers

- Uniplane, Two-Phase Controller

The ISL6265 is a multi-output controller with embedded gate

drivers. A single-phase controller powers the Northbridge

(VDDNB) portion of the CPU. The two remaining controller

channels can be configured for two-phase or individual

single-phase outputs. For uniplane CPU applications, the

ISL6265 is configured as a two-phase buck converter. This

allows the controller to interleave channels to effectively

double the output voltage ripple frequency and thereby

reduce output voltage ripple amplitude with fewer

components, lower component cost, reduced power

dissipation, and smaller area. For dual-plane processors, the

ISL6265 can be configured as independent single-phase

controllers powering VDD0 and VDD1.

• Precision Voltage Regulators

- 0.5% System Accuracy Over-temperature

• Voltage Positioning with Adjustable Load Line and Offset

• Internal Gate Drivers with 2A Driving Capability

• Differential Remote CPU Die Voltage Sensing

• Core Differential Current Sensing: DCR or Resistor

• Northbridge Lossless r_DS(ON)Current Sensing

• Serial VID Interface

- Two Wire Clock and Data Bus

- Supports High-Speed I²C

The heart of the ISL6265 is the patented R³Technology™,

Intersil’s Robust Ripple Regulator modulator. Compared with

the traditional buck regulator, the R³Technology™ has a

faster transient response. This is due to the R³modulator

commanding variable switching frequency during a load

transient.

- 0.500V to 1.55V in 12.5mV Steps

- Supports PSI_L Power-Saving Mode

• Core Outputs Feature Phase Shedding with PSI_L

• Adjustable Output-Voltage Offset

• Digital Soft-Start of all Outputs

• User Programmable Switching Frequency

• Static and Dynamic Current Sharing (Uniplane Core)

• Overvoltage, Undervoltage, and Overcurrent Protection

• Pb-Free (RoHS Compliant)

The Serial VID Interface (SVI) allows dynamic adjustment of

the Core and Northbridge output voltages independently and

in combination from 0.500V to 1.55V. Core and Northbridge

output voltages achieve a 0.5% system accuracy

over-temperature.

A unity-gain differential amplifier is provided for remote CPU

die sensing. This allows the voltage on the CPU die to be

accurately regulated per AMD mobile CPU specifications.

Core output current sensing is realized using lossless

inductor DCR sensing. All outputs feature overcurrent,

overvoltage and undervoltage protection.
