Applications Information
ON/OFF Pin
The LM3490 features a logic controlled ON/OFF pin that will
allow the output voltage to be disabled, or enabled, as need-
ed. The defined operating voltage range for this pin is 0.0V to
5.0V. The ON/OFF pin can not be left floating, as the output
status cannot be guaranteed. Additionally, the ON/OFF pin
should not be biased below ground potential as unpredictable
device behavior may occur.
Pulling the ON/OFF pin voltage to a value between the V
threshold and 5.0V will enable the output voltage. Pulling the

ON/OFF pin voltage to a value between the V
Ground potential will disable the output voltage. Although the
ON/OFF threshold is typically 725mV, and has no hysteresis,
the ON/OFF signal must rise and fall, cleanly and promptly,
from voltage levels that are below the V
the V
The ON/OFF pin has no internal pull-up or pull-down to es-
tablish a default condition and, as a result, this pin must be
terminated, either actively or passively, to an appropriate volt-
age level.
