34844
The 34844 is a SMARTMOS high efficiency, LED driver for use in backlighting LCD displays from 10" to 20"+.
Operating from supplies of 7.
0 to 28 V, the MC34844 is capable of driving up to 160 LEDs in 10 parallel strings.
Current in the 10 strings is matched to within 2%, and can be programmed via the I2C/SM Bus interface.
The 34844 also includes a Pulse Width Monitor (PWM) generator for LED dimming.
The LEDs can be dimmed to one of 256 levels, programmed through the I2C/SM Bus interface.
Up to 65,000:1 (256:1 PWM, 256:1 Current DAC) dimming r...
