Description
Input supply for internal bias and control circuitry. Need to locally bypass this pin to GND.
Enable control input. Logic high enables operation. Do not allow this pin to float or subject
to voltages greater than V
Signal (analog) ground. Place the bottom resistor of the feedback network as close as
possible to this pin for good load regulation.
No user function, connect this pin to GND.
Feedback pin. Connect this pin to the external resistor divider to set output voltage.
Power ground pin. Provides ground return path for the internal driver.
Switch pins. Connect these pins to the inductor and catch diode.
Input supply voltage. Connect a bypass capacitor locally from these pins to PGND.
Connect to system ground for low thermal impedance, but it cannot be used as a primary
GND connection.
