Next-Gen Mobile Processors

( 1 Jan 2006 )

Intersil Corporation introduces the ISL6260B multiphase core regulator and ISL6262 two-phase, integrated-driver core regulator. The ISL6260B is a multiphase regulator that uses external drivers and can to be programmed as 1-, 2-, or 3-phase. When combined with Intersil’s ISL6208 gate driver, the ISL6260B forms the basis for a portable power supply system to power Intel’s latest CPU (central processing unit) family for the notebook market, enabling phase-dropping at intermediate load levels. Phasedropping allows the device to be configured to alternate phases (2-phase to 1-phase, or 3-phase to 2-phase). The dynamic phase add-drop feature together with diode emulation mode at light load on the ISL6260B and ISL6262 maximize the efficiency over a wide load range to improve battery life. The modulator at the heart of this power system is created using Intersil’s patented R3 (robust ripple regulator) technology. Compared with traditional multiphase buck regulators, Intersil’s R3-based converters have faster transient response due to the R3 modulator commanding variable switching frequency during load transients.
