Board description and configuration

The board allows tuning several design parameters, giving the possibility to evaluate and optimize the
performance and switching characteristics of the power stage.
The user can select and mount the power switch of choice either in TO-220 or TO-247 package; the board also
allows installing an optional heatsink.
The demonstration board can be populated with isolated DC-DC converters in the standard SIP7 package to
supply the gate driving section, which significantly reduce the effort to supply the system and allow fast and easy
evaluation of the gate driving performances.
The board is compatible with the whole STGAP2S family in SO-8 package, so it is possible to evaluate the part
number of interest just by replacing the gate driver.
Figure 2 shows the position of the main components and connectors on the board.
