10 Layout
10.1 Layout Guidelines
- Place and route the power components first (C1, L1, C2).
- The input capacitor (C1) must be placed as close as possible from PVIN to PGND.
- The inductor must be placed as close as possible to the switch pin.
- All ground connections (shown in bold) must be on a common ground plane or form a star ground.
- Analog ground (AGND) and power ground (PGND), as well as the exposed thermal pad, must be tight together.
- The feedback network (R1, C3, R2) must be routed away from the inductor (L1) and should be grounded to the exposed thermal pad.
- The feedback network must sense and regulate the output voltage across the output capacitor to minimize load regulation.
