Description
Power supply input. Connect to the input filter capacitor (
Figure 1
).
Ground pin.
Enable pin. The device is in shutdown mode when voltage to this pin is
<
0.4V and
enabled when
>
1.0V. Do not leave this pin floating.
Feedback analog input. Connect directly to the output filter capacitor for fixed voltage
versions. For adjustable version external resistor dividers are required. The internal
resistor dividers are disabled for the adjustable version.
Switching node connection to the internal PFET switch and NFET synchronous
rectifier.
