DATASHEETISL6261A Single-Phase Core Regulator for IMVP-6® MNROoEbTCilROeEMCCMPOEUMNsMDIEESNDLD6R2EE8D8P4FLCOA CRENMEEWNTDEPSAIRGTNS FN6354 Rev 3.00 November 5, 2009 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. The ISL6261A provides three operation modes: the Continuous Conduction Mode (CCM), the Diode Emulation Mode (DEM) and the Enhanced Diode Emulation Mode (EDEM). To boost battery life, the ISL6261A changes its operation mode based on CPU mode si...
