Multi-Output Controller with Integrated MOSFET Drivers for AMD SVI Capable

Mobile CPUs

The ISL6265C is a multi-output controller with embedded gate

Features

drivers. A single-phase controller powers the Northbridge

• Core Configuration Flexibility

(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

ISL6265C 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 ISL6265C can be configured as

independent single-phase controllers powering VDD0 and

VDD1.

- Dual Plane, Single-Phase Controllers

- Uniplane, Two-Phase Controller

• 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

The heart of the ISL6265C 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.

• Serial VID Interface

- Two Wire Clock and Data Bus

- Supports High-Speed I²C

- 0.500V to 1.55V in 12.5mV Steps

- Supports PSI_L Power-Saving Mode

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.

• Core Outputs Feature Phase Shedding with PSI_L

• Adjustable Output-Voltage Offset

• Digital Soft-Start of all Outputs

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.

• User Programmable Switching Frequency

• Static and Dynamic Current Sharing (Uniplane Core)

• Overvoltage, Undervoltage, and Overcurrent Protection

• Pb-Free (RoHS compliant)

Applications

• AMD Griffin Platform CPU
