8. Layout
Some important guidelines for a good layout:
Keep the trace from the DRAIN pin to the MOSFET drain as short as possible
Keep the trace from the SOURCE pin to the MOSFET source as short as possible
Keep the area of the loop from the DRAIN pin, to the MOSFET drain, to the MOSFET
source, and to the SOURCE pin as small as possible. Make sure that the overlap of
this loop over the power drain track or the power source track is as small as possible.
Take care that the two loops do not cross each other.
Keep the track from the GATE pin to the gate of the MOSFET as short as possible
Use separate clean tracks for the XV and the GND pins. If possible, use a small
ground plane underneath the IC, which improves the heat dispersion.
