DESIGN FLOW
The placement of the input capacitors is highlighted in the following picture of the evaluation board:
2: Have a single point ground.
The ground connections for the feedback, soft-start, and enable components should be routed to the AGND pin of the
device. This prevents any switched or load currents from flowing in the analog ground traces. If not properly handled,
poor grounding can result in degraded load regulation or erratic output voltage ripple behavior.
