capacitor, the inductor, the SW pin, the GND_BOOST pin
and the ground plane, as shown by the dashed line in Figure
21. The other switching loop, the rectifier loop, is formed by
the input capacitor, the inductor, the diode, the output ca-
pacitor and the ground plane, as shown by the dotted line.
Arrange the components so that the switching current loops
curl in the same direction (see arrows in Figure 21). See also
