    Description of the functional blocks The description of the functional blocks of the daughterboard EVAL-1ED020I12F2-DB refer to Figure 5. All connections are shown only roughly, the detailed circuit is shown in Figure 8. In principle, the board can be separated into two parts, the primary and the secondary side. The primary side describes the low voltage area, the secondary the high-voltage area, which directly controls the power switch.
