Pin Function
Switch Node (Input): Internal power BIPOLAR collector.
Ground (Return): Ground.
Feedback (Input): 1.24V output voltage sense node. V_OUT =
1.24V ( 1 + R1/R2)
Enable (Input): Logic high enables regulator. Logic low
shuts down regulator.
Supply (Input): 2.5V to 10V input voltage.
Output Over-Voltage Protection (Input): Tie this pin to V_OUT
to clamp the output voltage to 34V maximum in fault
conditions. Tie this pin to ground if OVP function is not
required.
No connect. No internal connection to die.
Analog ground
Power ground
Ground (Return). Exposed backside pad.
