In applications with no access to a vertical sync, an onboard
oscillator operates the inverter burst rate at about 270Hz. In
this non-synchronous mode, minor display disturbances can
be found under certain video conditions. This performance
may
synchronization must be used when no disturbance can be
tolerated.

The Brightness control may be a voltage output DAC,
digital resistor or a simple 10K potentiometer, or other
voltage source, as shown in Figure 5. A 2.5V to 5V Logic
Level PWM signal from a micro-controller may also be
used as shown in Figure 5A.

Separate feedback loops for lamp current and open circuit
voltage regulation insure reliable strike under all operating
conditions, automatic over-voltage prevention with broken
or failed lamps, and accurate lamp current regulation.
A single input will accommodate negative and positive
vertical sync pulses at any pulse width.
