LAYOUT CONSIDERATIONS
Good layout is essential for stable power supply operation. Follow these guidelines for a clean PCB layout:
Separate the power ground and analog ground planes. Connect them together at one location.
Use four vias to connect the thermal pad to power ground.
Place VIN and VDD decoupling capacitors as close to the device as possible.
Use wide traces for VIN, VOUT, PGND and SW. These nodes carry high current and also serve as heat sinks.
Place feedback and compensation components as close to the device as possible.
Keep analog signals (FB, COMP) away from noisy signals (SW, SYNC, VBST).
Refer to TPS53311 evaluation module for a layout example.
