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 control input, active low. This pin can also function as soft-start control pin. A
capacitor connected from this pin to ground sets the ramp time to full current output.
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.
