資料

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 signals DPRSLRVR and DPRSTP#, and the FDE pin setting, to maximize the efficiency. In CPU active mode, the ISL6261A commands the CCM operation. When the CPU enters deeper sleep mode, the ISL6261A enables the DEM to maximize the efficiency at light load. Asserting the FDE pin of the ISL6261A in CPU deeper sleep mode will enable the EDEM to further decrease the switching frequency at light load and increase the regulator efficiency.
