3. Keep the switching node, SW, away from all sensitive
small signal nodes.
4. Flood all unused areas on all layers with copper.
Flooding with copper will reduce the temperature rise of
power components. You can connect the copper areas to
any DC net (PVIN, SVIN, VOUT, PGND, SGND, or any other
DC rail in your system).
5. Connect the VFB pin directly to the feedback resistors.
The resistor divider must be connected between VOUT
and SGND.
