The ISL6266 and ISL6266A are two-phase buck converter
regulators implementing IntelВ® 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 R3 Technologyв„ў,
Intersil’s Robust Ripple Regulator modulator. Compared with
traditional multiphase buck regulators, the R3 Technologyв„ў
has the fastest transient response. This is due to the R3
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 …
