Precision Multi-Phase Buck PWM

Controller for Intel‚ Mobile Voltage

Positioning IMVP-IV™and IMVP-IV+™

Features

• IMVP-IV™ and IMVP-IV+™ Compliant CORE Regulator

• Single and/or Two-phase Power Conversion

• “Loss-less” Current sensing for improved efficiency and

reduced board area

The ISL6217 Multi-Phase Buck PWM control IC, with

integrated half bridge gate drivers, provides a precision

voltage regulation system for advanced Pentium“ IV

microprocessors in notebook computers. Two-phase

operation eases the thermal management issues and load

demand of Intel’s latest high performance processors. 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

RDS(ON) and user selectable switching frequencies from

250kHz to 1MHz per phase.

Optional Discrete Precision Current Sense Resistor

• Internal Gate-Drive and Boot-Strap Diodes

• Precision CORE Voltage Regulation

−

0.8% system accuracy over temperature

• 6-Bit Microprocessor Voltage Identification Input

• Programmable “Droop” and CORE Voltage Slew Rate to

comply with IMVP-IV™ and IMVP-IV+™ specification

• Direct Interface with System Logic (STP_CPU# and

DPRSLPVR) for Deep and Deeper Sleep modes of

operation

The ISL6217 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™ and IMVP-IV+™ mobile VID

specification. The ISL6217 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”, provide excellent static and dynamic CORE voltage

regulation.

• Easily Programmable voltage setpoints for Initial “Boot”,

Deep Sleep and Deeper Sleep Modes

• Excellent Dynamic Response

−

Combined Voltage Feed-Forward and Average

Current Mode Control

• Overvoltage, Undervoltage and Overcurrent Protection

To improve efficiency at light loading, the ISL6217 can be

configured to run in single phase PWM in ACTIVE, DEEP or

DEEPER SLEEP modes of operation.

• Power-Good Output with internal blanking during VID and

mode changes

• User programmable Switching Frequency of 250kHz -

1MHz per phase

Another feature of this IC controller is the PGOOD monitor

circuit that is held low until CORE voltage increases, during

its soft-start sequence, to within 12% of the “Boot” voltage.

This PGOOD signal is masked during VID changes. Output

Overcurrent, Overvoltage and Undervoltage are monitored

and result in the converter latching off and PGOOD signal

being held low.

• Pb-Free Plus Anneal Available (RoHS Compliant)

The Overvoltage and Undervoltage thresholds are 112%

and 84% of the VID, Deep or Deeper Sleep setpoint,

respectively. Overcurrent protection features a 32 cycle

Overcurrent shutdown. PGOOD, Overvoltage, Undervoltage

and Overcurrent provide monitoring and protection for the

microprocessor and power system. The ISL6217 IC is

available in a 38 lead TSSOP.

NOTES:

1. Intersil Pb-free plus anneal products employ special Pb-free

material sets; molding compounds/die attach materials and 100%

matte tin plate termination finish, which are RoHS compliant and

compatible with both SnPb and Pb-free soldering operations. Intersil

Pb-free products are MSL classified at Pb-free peak reflow

temperatures that meet or exceed the Pb-free requirements of

IPC/JEDEC J STD-020.

CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
