The top side (component) layer for IRU3038 Eval board
is shown in Figure 2. The input capacitors are all located
close to the MOSFETs. All the decoupling capacitors,
charge pump capacitor and feedback components are
located close to IC. The feedback resistors are tied to
the output voltage at the point of regulation.
The PCB is 4-layers board, one layer is dedicated to
Power GND and the analog GND is kept separated from
the PGND and it is connected at a single point.
