TYPICAL APPLICATION

(Dual Layout with HIP6019)

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:

S - Short

O - Open

V - See IR or Harris parts list for the value

Table 2 - Dual layout component table.
