Fujitsu Siemens Computers has selected Intersil as the preferred supplier of power management ICs for all its PC motherboards.

Fujitsu Siemens Computers has selected Intersil as the preferred supplier of power management ICs for all its PC motherboards.

This is a major coup for Intersil whose multiphase power management solutions are already widely used on both Intel and AMD processor boards in PCs, file servers and portable information appliances.

Fujitsu Siemens Computers offers one of the world's most complete product and solution portfolios.

Its world-leading technology and innovative Information Technology products span the entire range of personal computing and enterprise computing needs.

Fujitsu Siemens Computers has selected Intersil's Endura motherboard power solutions based on a multiphase power controller IC from the HIP6300 series and one or more HIP6600 series mosfet drivers.

The multiphase controller family consists of five multiphase PWM controllers offering two- to four-phase controllers that regulate output currents as high as 100A or more.

The mosfet driver series includes the HIP6601A and HIP6603A single-phase synchronous buck mosfet drivers, and the HIP6602A dual-phase driver designed to drive four N-channel mosfets.

"Fujitsu Siemens selection of Intersil as their preferred power management solution provider further strengthens our position as the world's leader in microprocessor power control", said Rick Furtney, vice president and general manager of Intersil's Analog Business Unit.

"Fujitsu Siemens Computers is a leading provider of professional PCs, notebooks and workstations to business customers, and is Europe's leading supplier of PCs for home users and small offices".

Intersil's Endura multiphase pulse width modulation (PWM) control circuits offer unmatched precision and flexible scalability for applications requiring two, three or up to four phases of power control - three phases for today's Intel Pentium 4 and four phases for the next generation processors.

This multiphase control technology, pioneered by Intersil, offers manufacturers cost savings in components because phase balancing causes load current to be evenly distributed among phases allowing the use of less costly mosfets and phase staggering greatly increases the ripple frequency making it easier to filter to a very low ripple voltage with smaller filter components.

The Endura family includes high-efficiency solutions that are used in portable PCs and mobile information appliances as well as home gateway products.

Intersil's leadership position has grown, capturing over 5% of the AMD Athlon and Intel Pentium 4 processors and providing power management solutions for next generation desktop, portable and wireless communications devices.

The company is the first to introduce a complete cost effective power solution for new and next generation PCs that uses a multiphase power configuration to achieve unparalleled precision and efficiency.
