ISL6261 is Single-Phase Core Regulator manufactured by Renesas.
Single-Phase Core Regulator for IMVP-6® Mobile CPUs
FN9251 Rev 1.00 Sep 27, 2006
The ISL6261 is a single-phase buck regulator implementing lntel® IMVP-6® protocol, with embedded gate drivers.
The heart of the ISL6261 is the patented R3 Technology™, Intersil’s Robust Ripple Regulator modulator. pared with the traditional multi-phase buck regulator, the R3 Technology™ has faster transient response. This is due to the R3 modulator manding variable switching frequency during a load transient. lntel® Mobile Voltage Positioning (IMVP) is a smart voltage regulation technology effectively reducing power dissipation in lntel® Pentium processors. To boost battery life, the ISL6261 supports DPRSLRVR (deeper sleep) function and maximizes the efficiency via automatically changing operation modes. At heavy load in the active mode, the regulator mands the continuous conduction mode (CCM) operation. When the CPU enters deeper sleep mode, the ISL6261 enables...
