I-LITE, 8.0 WATT LED DRIVER
(Common-Cathode, One to Six Channels)
B D C
GENERAL DESCRIPTION
The ACI-A038040-1855 is designed to drive up to 6 parallel channels of series connected LEDs. The number of channels and current per channel are configurable per Table 1 on Page 3, by setting a fourposition switch located on the driver, enabling the driver to support a wide range of displays. Operating as a true constant current source, the driver provides a complete integrated solution that operates from a nominal +12V source.

Channels Driven
Caution: When selecting the number of channels to be driven and current per channel from one of the configurations in Table 1 above, you must ensure that the Forward-Drop Voltage (Vf) in your application does not exceed the Vf max value specified in Table 1. The Nominal Input Current Draw, based on Vin, can be calculated from the following equation:
Nominal Input Current Draw (A) = Iout per Channel (mA) X Number of Channels X Vf (V) X 0.0011
