LM2651MTC-3.3
Switched-node connection, which is connected with the source of the internal high-side
MOSFET.
Main power supply pin.
Bootstrap capacitor connection for high-side gate drive.
Input supply voltage for control and driver circuits.
Shutdown and Soft-start control pin. Pulling this pin below 0.3V shuts off the regulator. A
capacitor connected from this pin to ground provides a control ramp of the input current.
Do not drive this pin with an external source or erroneous operation may result.
Output voltage feedback input. Connected to the output voltage.
Compensation network connection. Connected to the output of the voltage error amplifier.
No internal connection.
Low-noise analog ground.
Power ground.
