Figure 3 - Typical application of US3007 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 applications.
Components that need to be modified to make the dual layout work for US3007 and HIP6019.
