Pin Function
Soft Start: Place a capacitor from this pin to ground to program the soft start time.
Do not leave floating, 100pF minimum C SS is required.
Analog Ground: Connect to central ground point where all high current paths meet
(C IN , C OUT , PGND) for best operation.
Input Voltage: Connect a capacitor to ground to decouple the noise.
Power Ground.
Output Voltage: The output of the regulator. Connect to SNS pin. For adjustable option,
connect to feedback resistor network.
Switch: Internal power MOSFET output switches before Inductor
Enable: Logic high enables operation of the regulator. Logic low will shut down the device.
Do not leave floating.
Sense: Connect to V OUT as close to output capacitor as possible to sense output voltage.
Power Good: Open drain output for the Power Good (PG) indicator. Use a pull up resistor
from this pin to a voltage source to detect a power good condition.
Not Internally Connected.
Feedback: Connect a resistor divider from the output to ground to set the output voltage.
