Precision Single-Phase Buck PWM

Controller for Intel Mobile Voltage

Positioning IMVP-IV™ and IMVP-IV+™

The ISL6218 Single-Phase Buck PWM control IC, with

integrated half bridge gate driver, provides a precision

voltage regulation system for advanced Pentium-M

microprocessors in notebook computers. This control IC also

features both input voltage feed-forward and average current

mode control for excellent dynamic response, “Loss-less”

current sensing using MOSFET r_DS(ON), and user selectable

switching frequencies from 250kHz to 500kHz per phase.

Features

• IMVP-IV^™Compliant CORE Regulator

• Single-Phase Power Conversion

• “Loss-less” Current Sensing for Improved Efficiency and

Reduced Board Area

- Optional Discrete Precision Current Sense Resistor

• Internal Gate Drive and Boot-Strap Diode

• Precision CORE Voltage Regulation

- 0.8% System Accuracy Over-temperature

• 6-Bit Microprocessor Voltage Identification Input

The ISL6218 includes a 6-bit digital-to-analog converter

(DAC) that dynamically adjusts the CORE PWM output

voltage from 0.700V to 1.708V in 16mV steps, and conforms

to the Intel IMVP-IV^™mobile VID specification. The ISL6218

also has logic inputs to select Active, Deep Sleep and

Deeper Sleep modes of operation. A precision reference,

remote sensing and proprietary architecture with integrated

processor-mode compensated “Droop” provides excellent

static and dynamic CORE voltage regulation.

• Programmable “Droop” and CORE Voltage Slew Rate to

Comply with IMVP-IV^™Specification

• Discontinuous Mode Of Operation for Increased Light

Load Efficiency in Deep and Deeper Sleep Mode

• Direct Interface with System Logic (STP_CPU and

DPRSLPVR) for Deep and Deeper Sleep Modes of

Operation

• Easily Programmable Voltage Setpoints for Initial “Boot”,

Deep Sleep and Deeper Sleep Modes

Another feature of the ISL6218 IC controller is the internal

PGOOD delay circuit that holds the PGOOD pin low for

3ms to 12ms after the VCCP and VCC_MCH regulators are

within regulation. This PGOOD signal is masked during VID

changes. Output overvoltage and undervoltage are

monitored and result in the converter latching off and

PGOOD signal being held low.

• Excellent Dynamic Response

- Combined Voltage Feed-Forward and Average Current

Mode Control

• Overvoltage, Undervoltage and Overcurrent Protection

• Power-good Output with Internal Blanking During VID and

Mode Changes

The overvoltage and undervoltage thresholds are 112% and

84% of the VID, Deep or Deeper Sleep setpoint. Overcurrent

protection features a 32 cycle overcurrent shutdown.

PGOOD, Overvoltage, Undervoltage and Overcurrent

provide monitoring and protection for the microprocessor

and power system. The ISL6218 IC is available in a

38 Ld TSSOP and 40 Ld QFN package.

• User Programmable Switching Frequency of 250kHz to

500kHz

• Pb-Free Plus Anneal Available (RoHS Compliant)
