InfiniBand +12V Bulk and +5V Auxiliary

Power Controller

The ISL6160 is designed to address the unique power

requirements of the InfiniBand (IB) industry initiative

providing independent power control of both the VB(bulk)

(+12V) and the VA(auxiliary) (+5V) power rails for a single

port. This device can be implemented in both IB Class I (non

isolated) and Class II (isolated) Power Topology applications.

The ISL6160, along with an N-Channel power MOSFET and

a minimal number of passive components provides soft

starting ramps of both the VB and VA voltages for an IB

module. It also provides accurate and consistent current

regulated outputs for a determined period of time before

latch-off in the presence of overcurrent (OC) conditions.

In addition the ISL6160 provides the enable signal to the on

module DC-DC converter either upon module insertion to

chassis or from a wake event request.

See Figure 1 for typical application usage.

NOTE: Intersil Pb-free products employ special Pb-free material sets; molding

compounds/die attach materials and 100% matte tin plate termination finish, which

is compatible with both SnPb and Pb-free soldering operations. Intersil Pb-free

products are MSL classified at Pb-free peak reflow temperatures that meet or

exceed the Pb-free requirements of IPC/JEDEC J Std-020B.
