Milpitas, Calif.—Intersil's ISL6260C, ISL6261A, and ISL6262A core controllers meet Intel's next-generation (Core Duo and Core 2 Duo) mobile platform requirements, providing improved reporting accuracy for power dissipation, higher efficiency, and even better transient response.
"The ability to report power dissipation to the CPU is an important step towards optimizing the operation of the CPU and enhancing overall efficiency and battery usage, as well as overall system thermal performance," said Majid Kafi, director of the Notebook Power products group. "Intersil's new family of controllers also offers flexible solutions for customers who are transitioning from Intel Napa platforms to the Santa Rosa platform. They can use their similar layout and still have the improved performance that our new controllers offer. Improved efficiency and faster transient response will result from being able to use higher tolerance inductors in DC resistance measurement settings and reduce the total cost."
The ISL6260C multiphase controller, together with the ISL6208 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 44 amps. The ISL6261A offers single-phase operation with an internal driver for LV/ULV applications up to 25 amps. The ISL6260C and ISL6262A are also able to add and drop phases for improved efficiency and flexibility.
These core controllers feature Intersil's R3 (Robust Ripple Regulator) technology to facilitate faster transient response. Compared with conventional controllers, these controllers reportedly stabilize current flow and allow less time between wave peaks in a regulator circuit. Key features include precision core voltage regulator with enhanced load line accuracy and 0.5 percent system accuracy over temperature; user-programmable switching frequency; and 7-bit VID input. These controllers support multiple current- sensing approaches.
