2.1
In Figure 3 shown examples are based on device power supply concept and implementation. Alternative
implementations are also acceptable and must be evaluated within application by customer.

The three supply domains VDD, VDDP and VDDEBU of TC1793 should be decoupled separately
(see decoupling placement example in Figure 3).
Type of capacitors:
All supply pins should be connected first to the dedicated decoupling capacitor and then from the
capacitors over vias to the power planes.
All VSS pins should be connected to the GND.
The decoupling capacitors should be placed directly under the IC or if necessary, some capacitors
can be placed on top layer close to the supply pins of the IC.
Ground plane on bottom layer can be used to connect the capacitors. If no plane is used, they
should be connected with vias to the GND layer.
Multiple vias should be used at capacitors to get a low impedance connection between capacitors
and POWER/GND planes or pins.
All capacitors must be placed as close as possible to the related supply pin group.
