PG
Power Good.Output open drain to indicate the status of VOUT via
monitoring the FB pin. This pin is pulled low when the voltage is
outside the limits, during thermal shutdown and if either VCNTL or VIN
go below their thresholds.

Enable Pin. Driving this pin low will disable the part. When left
floating an internal current source will pull this pin high and enable
it.

VIN
Power Input Pin for current supply. Connect a decoupling capacitor
(≥10µF) as close as possible to the pin for noise filtering

VCNTL
BIAS supply for the controller, recommended 5V. Connect a
decoupling capacitor (≥1µF) as close as possible to the pin for
noise filtering.
