1. Place the switching regulator inductor (L3) close to SW_OUT Pins (Pin15, Pin16).
2. The SW_OUT output traces should be as wide as possible.
3. The GNDX pins (Pin17, Pin18) should be connected to the main PCB ground plane, with the device GND pins of the PS8625 connected to separate GND island (GNDA) for the device.
The GND island (GNDA) should be connected to the main GND plane (GND) with a single-point connection by use of a wide PCB trace.
4. Place the 4.7uF decoupling Capacitor (C4) for VDDIOX close to VDDIOX pin.
5. The GND of the 4.7uF capacitor (C4) for VDDIOX should be placed close to the GND of 4.7uF capacitor (C5) behind Inductor.
6. Place the bead (L2) for VDDIOX close to PS8625.
