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 ( FIGURE 1).
Switching node connection to the internal PFET switch and NFET synchronous
rectifier.
