LAYOUT CONSIDERATIONS
The performance of a dc-to-dc converter depends highly on how
the voltage and current paths are configured on the printed
circuit board (PCB). Optimizing the placement of sensitive
analog and power components are essential to minimize output
ripple, maintain tight regulation specifications, and reduce
PWM jitter and electromagnetic interference.

Vias should populate, mainly around the positive and negative
terminals of the input and output capacitors, alongside the
source of Q1/Q2, the drain of Q3/Q4, and the inductor.
