Power ground. This pin is the ground connection for the emitter of the power switching transistor. Connection
to a good ground plane is essential.
High current switch pin. This pin connects internally to the collector of the power switch. The open voltage
across the power switch can be as high as 40 V. To minimize radiation, use a trace as short as practical.
