HIGHLIGHTS (CONTINUED)
The LXM1615-03-xx output current can be adjusted lower
by changing the value of one resistor (R10) on the PCB.
The following table shows the new output current values:
•
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.

The Brightness control may be a voltage output DAC, or
other voltage source as shown in Figure 5. A 3.3V Logic
Level PWM signal from a micro-controller may also be
used as shown in Figure 5A.
If synchronization to the video frame rate is desired,
connect the vertical sync pulse from the system video
controller to the VSYNC input.
synchronization is desired, connect VSYNC to ground.
If you need to turn the inverter ON/OFF remotely, use the
+3.3V Logic Supply pin.
Connect VHI to high voltage wire from the lamp.
Connect VLO to the low voltage wire (wire with thinner
insulation). Never connect VLO to circuit ground as this
will defeat lamp current regulation. If both lamp wires
have heavy high voltage insulation, connect the longest
wire to VLO. This wire is typically white.
Also available in higher power single lamp inverters
LXM1612-xx-xx,
LXM1622-xx-xx and Quad Output LXM1641-01
versions for multiple lamp applications.
A single input will accommodate negative and positive
vertical sync pulses at any pulse width.
