Intersil Introduces New Generation Of Controllers For Intel Montevina Platform

Intersil Corp. introduced new power management ICs that will be designed into notebook, server and desktop computers based on Intel’s upcoming Montevina platform. Intersil’s new ISL6266A chip is a two-phase core controller designed to improve the efficiency and performance of systems based on this new generation of Intel Mobile, Core 2 Duo and Quad Core CPUs.

The ISL6266A features Intersil’s patented R³Technology ™ (Robust Ripple Regulator) which commands variable switching frequency during load transient events and is said to provide the fastest transient response of any comparable IC on the market. R³ ensures fast and highly efficient performance across all the entire loadline of CPU operation.

With enhanced load line accuracy, the ISL6266A ensures Intel specification compliance in mass production and, along with a 0.5% system accuracy over temperature, the overall output decoupling requirements leading to lowest total output capacitor cost.

The ISL6266A also features fault-proof capability in the form of overvoltage, undervoltage and overcurrent protections to protect the regulator, the CPU and the upstream power supply. In addition, the ISL6266A features power and thermal monitors, which is said to make it one of the most safety-optimized controllers on the market for the latest Intel platform.

All of the ISL6266A&’s features are incorporated into a small 48-lead, 7 x 7mm package that is compatible with existing board layouts that use Intersil&’s previous generation of power management ICs. The company claims that this reverse compatibility packaging will save costly redesign cycles for computer makers transitioning their product lines to the new Intel platform.

The ISL6266A is available now in a 48-lead QFN package and priced at $2.86 each in 1,000-unit quantities.
