ISL6262AIRZ-T Product details

The ISL6262A 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 ISL6262A is the patented 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 ISL6262A supports DPRSLPVR (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 with medium
load in active mode, the ISL6262A smoothly disables one
phase and operates in one-phase CCM. When the CPU
enters deeper sleep mode, the ISL6262A enables diode
emulation to maximize the efficiency at light load.
For better system power management of the portable
computer, the ISL6262A also provides a CPU power monitor
output. The analog output at the power monitor pin can be
fed into an A/D converter to report instantaneous or average
CPU power.
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 ISL6262A.
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.
