Name
Function
VSEN
Regulated voltage sense pin for OVP and UVP protections and PGOOD.
Connect to the output regulated voltage, or to the output resistor divider if
the regulated voltage is higher than the reference.
PGOOD
Open drain output set free after SS has finished and pulled low when VSEN
is outside the relative window. Pull up to a voltage equal or lower than VCC.
If not used it can be left floating.
