ISL6217
FN9089.3
Precision Multi-Phase Buck PWM
Controller for Intel? Mobile Voltage
Positioning IMVP-IV?and IMVP-IV+?
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.
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.
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.
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.

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.
