Control input pin. Forcing this pin above 1.5V enables the IC. Forcing this pin
below 0.6V shuts down the IC. When the IC is in shutdown mode, all functions
are disabled to decrease the supply current below 1µA
Ground pin
Power switch output pin. Inductor connection to drain of the internal PFET and
NFET switches
Supply input pin. Bypass to GND with a 4.7µF or greater ceramic capacitor
Feedback pin. Connect it with an external resistor divider network to program
the system output voltage
