Applications
wire- -wrap or plug- -in prototype board. In order to ensure
proper device operation and stability, it is important to
minimize the lead length and the associated inductance of
the ground pin. This pin must connect as directly as possible
to the printed circuit ground plane and should not be bent or
Bypass

offset by the board layout. The Power Switch Circuit pin can
be offset if additional layout creepage distance is required.
Due to the potentially high rate of change in switch current,
a capacitor (if used), at pin 2, should have traces as short as
possible, from pin 2 and ground. This will significantly
reduce the level of switching noise that can be imposed upon
the feedback control signal.
