Two-phase Core Controllers
(Montevina, IMVP-6+)
The ISL6266 and ISL6266A are two-phase buck converter
regulators implementing Intel? IMVP-6 protocol with
embedded gate drivers. Both converters use interleaved
channels to double the output voltage ripple frequency and
thereby reduce output voltage ripple amplitude with fewer
components, lower component cost, reduced power
dissipation, and smaller real estate area.
The ISL6266A utilizes the patented R 3 Technology?,
Intersil’s Robust Ripple Regulator modulator. Compared with
traditional multiphase buck regulators, the R 3 Technology?
has the fastest transient response. This is due to the R 3
modulator commanding variable switching frequency during
load transient events.
Intel Mobile Voltage Positioning (IMVP) is a smart voltage
regulation technology, which effectively reduces power
dissipation in Intel Pentium processors. To boost battery life,
the ISL6266A supports DPRSLRVR (deeper sleep),
DPRSTP# and PSI# functions, which maximizes efficiency
by enabling different modes of operation. In active mode
(heavy load), the regulator commands the two phase
continuous conduction mode (CCM) operation. When PSI#
is asserted in active mode (medium load), the ISL6266A
operates in one-phase CCM. When the CPU enters deeper
sleep mode, the ISL6266A enables diode emulation to
maximize efficiency.
For better system power management, the ISL6266A

specifications. Current sensing can be realized using either
lossless inductor DCR sensing or discrete resistor sensing.
A single NTC thermistor network thermally compensates the
gain and the time constant of the DCR variations.
The ISL6266 also includes all the functions for IMVP-6+
core power delivery. In addition, it has been optimized for
use with coupled-inductor solutions. More information on the
differences between ISL6266 and ISL6266A can be found in
the “Electrical Specifications” on page 3 and the “ISL6266
Features” on page 21.

NOTE: These Intersil Pb-free plastic packaged products employ special
Pb-free material sets, molding compounds/die attach materials, and
100% matte tin plate plus anneal (e3 termination finish, which is 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.
