Layout Guidelines
Keep VIN and GND traces as wide as possible to reduce trace impedance. The wide areas are also an advantage from the view point of heat dissipation.
Place the input capacitor and output capacitor as close to the device as possible to minimize trace impedance.
Provide sufficient vias for the input capacitor and output capacitor.
Keep the SW trace as physically short and wide as practical to minimize radiated emissions.
Do not allow switching current to flow under the device.
Connect a separate VOUT path to the upper feedback resistor.
Make a Kelvin connection to the GND pin for the feedback path.
Place a voltage feedback loop away from the high-voltage switching trace, and preferably has ground shield.
Make the trace of the FB node as small as possible to avoid noise coupling.
Make the GND trace between the output capacitor and the GND pin as wide as possible to minimize its trace impedance.
