via monitoring the FB pin.
This pin is pulled low when the voltage is outside the limits, during thermal shutdown and
if either V
CNTL
or V
IN
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.
