Rev 1.00
December 23, 2008 Two-Phase Core Controller (Santa Rosa, IMVP-6+)
The ISL6262A is a two-phase buck converter regulator
implementing IntelВ® 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 Technologyв„ў,
Intersil’s Robust Ripple Regulator modulator. Compared with
the traditional multiphase buck regulator, the R3
Technologyв„ў has the fastest transient response. This is due
to the R3 modulator commanding variable switching
frequency during a load transient.
IntelВ® Mobile Voltage Positioning (IMVP) is a smart voltage
regulation technology, which effectively reduces power
dissipation in IntelВ® 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. …
