May 15, 2006 Two-Phase Core Regulator for IMVP-6 Mobile CPUs
The ISL6262 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 ISL6262 is R3 Technology™, 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.
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. …
