8.4 Layout

8.4.1 Layout Guidelines

• Make sure the VIN and GND traces are 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.

• Connect a separate VOUT path to VOS pin.

• Place a voltage feedback loop away from the high-voltage switching trace, and preferably has ground shield.

• Make sure the GND trace between the output capacitor and the GND pin are as wide as possible to minimize

the trace impedance.
