7 Layout

The printed circuit board (PCB) layout is a critical but often under-appreciated step in achieving proper performance and reliability, especially for switch-mode power supplies. Errors in the PCB layout cause misbehavior including poor output voltage regulation, switching jitter, and even device failure.
