I-DRIVE, 12 WATT LED DRIVER
(Single Channel 150V, 0-80mA)
GENERAL DESCRIPTION
The ACI-C150080-1968 represents the 3rd generation of I-
Drive technology used for powering LED backlights.
Operating as a true constant current source and capable
of driving up to 50 LEDs in series. This driver provides a
complete integrated solution that is regulated over an
input range of +8V to +18V.
Simple to connect and operate, this driver solution is
capable of providing precise control to support dimming
applications with a minimum of 3000:1.
This unit features enable and intensity control inputs.
