Power Good output flag: the pin is open drain and it is forced low if the
output voltage is lower than 90 % of the programmed voltage. If not used, it
can be left floating.
Input bias supply. This pin supplies the internal logic to drive the power
N-channel MOSFET that realize the voltage conversion. Connect directly to
V
The voltage connected to this pin MUST always be higher or equal that V
Enables the device if a voltage higher than 1 V is applied.
When pulled low, the device is in low-power consumption: everything inside
the controller is kept OFF.

Power supply voltage. This pin is connected to the drain of the internal
N-channel MOSFET.
Filter to GND with capacitor larger than the one used for V
Not internally connected.
Regulated output voltage. This pin is connected to the source of the
internal N-mos. MLCC capacitor are supported. Filter to GND with
capacitor smaller than the one used for V
