... FAN2558/FAN2559 General PCB Layout Considerations For optimum device performance, careful circuit layout and grounding techniques must be used. Establishing a small local ground, to which the GND pin, and the output and bypass capacitors are connected, is recommended. The input capacitor should be grounded to the main ground plane. The quiet local ground is then routed back to the main ground plane using feed through via ...
