57 / 60 page ![]() Data Sheet ADP5360 Rev. 0 | Page 57 of 60 PCB LAYOUT GUIDELINES Poor layout can affect ADP5360 performance, causing EMI and electromagnetic compatibility (EMC) problems, ground bounce, and voltage losses, as well as affect regulation and stability. A good layout is implemented using the following guidelines: • Place the decoupling capacitor, inductor, input capacitor, and output capacitor as close as possible to the ADP5360. • Use a ground plane with several vias connecting to the component side ground to further reduce noise interference on sensitive circuit nodes. • Use a dedicated trace to connect the BSNS pin to the battery pack output node for accurate sensing of the battery voltage. • Use 0603 size or 0402 size resistors and capacitors to achieve the smallest possible footprint solution on boards where space is limited.
