Connection Diagram and Package Mark Information
Pin Descriptions
Pin #
Name
Description
1V
IN
Power supply input. Connect to the input filter capacitor ( Figure 1).
2
GND
Ground pin.
3
EN
Enable input. The device is in shutdown mode when voltage to this pin is <0.4V and
enable when >1.0V. Do not leave this pin floating.
4
FB
Feedback analog input. Connect to the output filter capacitor for fixed voltage
versions. For adjustable version external resistor dividers are required ( Figure 2).
The internal resistor dividers are disabled for the adjustable version.
5
SW
Switching node connection to the internal PFET switch and NFET synchronous
rectifier.
