Intersil has introduced the world's first single hot-swap controller IC designed specifically for InfiniBand communications modules. InfiniBand is a new gigabit high-speed communications specification for midrange and high-end servers and data storage networks and is backed by an industry association of over 200 members. The new Endura ISL6160 controller IC allows InfiniBand module manufacturers to make major savings in board space, design costs and time to market.

The ISL6160 precisely controls power to InfiniBand communications modules by providing protection from damaging surges and allowing safe replacement of an InfiniBand module (hot swap) without shutting the server or system down.

It is available as a complete turnkey InfiniBand power solution with Intersil's HIP6006 pulsewidth modulation DC/DC controller in a reference design and evaluation platform (ISL6160EVAL2) that is backed by Intersil's engineering and industry experience.

Intersil is a member of the InfiniBand Trade Association, and worked with users and manufacturers to design the ISL6160 and the total power control solution needed to ensure reliable, uninterrupted service in these server systems.

The ISL6160 provides independent power control and soft-starting ramps of both the VB (bulk, +12V) and the VA (auxiliary, +5V) power rails required for every InfiniBand module.

It can be configured for Class I or Class II, nonisolated and isolated, topologies.

It also provides accurate and consistent current regulated outputs for a determined period of time before latch-off in the presence of overcurrent conditions.

On module insertion to chassis or from a wake event request, the ISL6160 supplies an enable signal to activate the on-module DC/DC convertor.

According to Intersil, no other InfiniBand hot swap solution is as compact or cost-effective.

The ISL6160 complete with evaluation system and reference design is available now.
