Is there an evaluation board available?
Yes, there is an evaluation board available through your local
Intersil sales office. The HIP1011EVAL1 board (Figure 4) is a
simple board designed to demonstrate and evaluate the
HIP1011 using an external PWRON signal simulating a PCI
Hot Plug environment. The HIP1011EVAL1 board comes in 2
parts, the mother board with the HIP1011, MOSFETs and
external components and a load board simulating a ‘typical’
PCI load with adequate space for modifying the existing load
or to add an electronic load. Even with a number of available
test points the HIP1011 implementation space is still very
efficient. In addition, the demo board offers adequate space to
evaluate the application note discussions.
