• The BRITE/BOOST control may be a voltage output
DAC, or other voltage source as shown in Figure 11. A
5V Logic Level PWM signal from a micro-controller may
also be used as shown in Figure 12.
• If synchronization to the video frame rate is desired,
connect the vertical sync pulse from the system video
controller to the VSYNC input. If no video synchronization
is desired, connect VSYNC to ground.
• If you need to turn the inverter ON/OFF remotely, connect
a 2.4V to 5V logic signal to the SLEEP input. If remote
ON/OFF is not needed, connect the SLEEP input to VIN or
other voltage source between 2.4V and 5V.
• Connect VOUT1 to the high voltage supply wire from the
lamp. Connect VOUT2 to the high voltage return wire from
the lamp.
Also available in other wide range dimming single lamp
inverters LXM1612-xx-xx, LXM1615, Dual Output
LXM1621-01, LXM1622-xx-xx and Quad Output
LXM1641-01 versions for multiple lamp applications.
