Intersil Introduces New Family of Core Controllers for Intel®‘s Mobile Platform
Intersil Corp. introduced a new family of core controllers for meeting Intel's next-generation (Core Duo and Core 2 Duo) mobile platform. These devices offer improved accuracy in power dissipation reporting and industry-leading transient response and efficiency enabled by Intersil's patented R3 (Robust Ripple Regulator) Technology.™ Intersil's new family of controllers reports the CPU power consumption through a highly accurate continuous analog output signal. Compared with conventional controllers, Intersil's R3 controllers stabilize current flow and allow less time between wave peaks in a regulator circuit.
To boost battery life, the ISL6260C, ISL6261A and ISL6262A support DPRSLRVR (deeper sleep) functions and maximize efficiency by automatically changing operation modes. At heavy loads in the active mode, these controllers command the continuous conduction mode (CCM) operation. When the CPU enters a deeper sleep mode, the controllers enable diode emulation to maximize the efficiency at light loads. The ISL6260C, ISL6261A and ISL6262A are part of Intersil's growing profile of Santa Rosa-compatible parts for Intel reference designs.
These core controllers feature Intersil's R3 Technology to enable faster transient response. The ISL6260C multiphase controller – together with ISL6208 external gate driver – provides a complete solution to power Intel's mobile microprocessors. It offers an up to three-phase solution for CPU core power. The ISL6262A has two integrated drivers and powers CPUs of up to 44A. The ISL6261A offers single-phase operation with an internal driver for LV/ULV applications up to 25A of CPU current. The ISL6260C and ISL6262A are also able to add and drop phases for improved efficiency and flexibility. This family of devices features power management innovations from the Notebook Power group. These parts are designed to meet the exacting specifications of laptop and mobile device manufacturers.
Among the controller's key features: a precision core voltage regulator with enhanced load line accuracy and 0.5% system accuracy over temperature; user-programmable switching frequency; a microprocessor voltage identification 7-bit VID input; supports multiple current sensing approaches; differential remote voltage sensing; and a CPU power monitor. The target applications are all notebook PCs powered with Intel's Core Duo or Core 2 Duo; blade servers powered with Intel's Core Duo or Core 2 Duo; and embedded applications powered with Intel's Core Duo or Core 2 Duo.
The ISL6260C is available now in a 40-lead, 6x6 QFN package and is priced at $3.25 each. The ISL6261A is available now in 40-lead, 6x6 QFN (tape and reel option available) packages or 48-lead, 7x7 QFN packages (tape and reel option available) and is priced at $3.50 each. The ISL6262A is available now in a 48-lead, 7x7 QFN package and is priced at $3.75 each. All prices are in 1,000-unit quantities.
