PRECISION ENABLE
The LM26420 features independent precision enables that
allow the converter to be controlled by an external signal. This
feature allows the device to be sequenced either by a external
control signal or the output of another converter in conjunction
13
with a resistor divider network. It can also be set to turn on at
a specific input voltage when used in conjunction with a re-
sistor divider network connected to the input voltage. The
device is enabled when the EN pin exceeds 1.04V and has a
150mV hysteresis.
