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+} _RR21^{}
Enable (Input): Logic high enables regulator. Logic low shuts down regulator.
Supply (Input): 2.5V to 10V input voltage.
Output Overvoltage 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.
Exposed backside pad.
