ISL6160 TM Data Sheet August 2001 File Number 9028 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 po
