Figure 16 shows the pin map of this device for the available package. Figure 17 shows a 3D image of the placement

of the most critical components required to implement the PE25203 IC. All components are placed on the top layer of

the PCB. In the PE25203 EVK, the IC is placed as shown in Figure 16 where the Vin voltage is on the right side and

the VX voltage (output voltage from IC that needs to be filtered) is on the left side. Similarly, for other designs, the

PE25203 IC can be placed in the opposite direction, but components should be placed as close as possible to the

PE25203 IC as shown in Figure 17.
