The ISL6261A is a single-phase buck regulator implementing lntel® IMVP-6® protocol, with embedded gate drivers. lntel® Mobile Voltage Positioning (IMVP) is a smart voltage regulation technology effectively reducing power dissipation in lntel® Pentium processors.
The heart of the ISL6261A is the patented R3 Technology™, Intersil’s Robust Ripple Regulator modulator. Compared with the traditional multi-phase buck regulator, the R3 Technology™ has faster transient response. This is due to the R3 modulator commanding variable switching frequency during a load transient.
