Figure 4 - Typical application of IRU3007 in a dual layout with HIP6019 for an on-board DC-DC converter
providing power for the Vcore, GTL+, Clock supply as well as an on-board 3.3V I/O supply for the
Deschutes and the next generation processor application.
Components that need to be modified to make the dual layout work for HIP6019 and IRU3007:
