ISL6160
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.
