Brightness Control Using a Potentiometer
The LS460 brightness control is done by applying a DC bias of 0
to 2.5V to the brightness control pins. Unlike the single tube invert-
ers like the LS380s, brightness control for dual tube inverters can-
not be accomplished with a potentiometer. The reason for this is
that the LS460 has a voltage follower, or a sub-regulator built into
the unit to synchronize both outputs. This voltage follower compen-
sates for resistive load to the brightness control circuitry.
Mean Time Between Failures (MTBF)
By using the MIL-HDBK 217E Condition Ground Benign
method, the MTBF for the LS460 is calculated at 787,407
hours.

However, by using a voltage separator circuit consisting of a poten-
tiometer, a virtual brightness control by potentiometer can be
achieved.
Note that current which will run between the brightness
control pin will be in a trivial 3.0µA range.
