Switched-node connection, which is connected with the source of the internal high-side
MOSFET.
Main power supply input pin. Connected to the drain of the high-side MOSFET.
Bootstrap capacitor connection for high-side gate drive.
Input 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.
A constant monitor on the output voltage. PGOOD will go low if the output voltage
exceeds 110% or goes below 80% of its nominal.
A capacitor between this pin to ground sets the delay from the output voltage reaches
80% of its nominal to when the undervoltage latch protection is enabled and PGOOD pin
goes low.
Low-noise analog ground.
Power ground.
