Two-Phase Core Regulator for IMVP-6
Mobile CPUs
The ISL6262 is a two-phase buck converter regulator
implementing Intel® IMVP-6 protocol, with embedded gate
drivers. The two-phase buck converter uses two interleaved
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 real estate area.
The heart of the ISL6262 is R3 Technology™, Intersil’s
Robust Ripple Regulator modulator. Compared with the
traditional multiphase buck regulator, the R3 Technology™
has the fastest transient response. This is due to the R3
modulator commanding variable switching frequency during
a load transient.
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 ISL6262 supports DPRSLRVR (deeper sleep),
DPRSTP# and PSI# functions and maximizes the efficiency
via automatically enabling different phase operation modes.
At heavy load operation of the active mode, the regulator
commands the two phase continuous conduction mode
(CCM) operation. While the PSI# is asserted at the medium
load in the active mode, the ISL6262 smoothly disables one
phase and operates in a one-phase CCM. When the CPU
enters deeper sleep mode, the ISL6262 enables diode
emulation to maximize the efficiency at the light load.
A 7-bit digital-to-analog converter (DAC) allows dynamic
adjustment of the core output voltage from 0.300V to 1.500V.
A 0.5% system accuracy of the core output voltage over
temperature is achieved by the ISL6262.
A unity-gain differential amplifier is provided for remote CPU
die sensing. This allows the voltage on the CPU die to be
accurately measured and regulated per Intel IMVP-6
specifications. Current sensing can be realized using either
lossless inductor DCR sensing or precision resistor sensing.
A single NTC thermistor network thermally compensates the
gain and the time constant of the DCR variations.

NOTE: 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.
