General Description
The SL8411 is an average current mode control LED driver IC operating in a constant off-time
mode. SL8411 does not produce a peak-to-average error, and therefore greatly improves accuracy,
line and load regulation of the LED current without any need for loop compensation or high-side
current sensing. The output LED current accuracy is ±2%.
The SL8411 can be powered from an 8.0 - 100V supply. PWM & Linear dimming input is provided
that accepts an external control TTL compatible signal. The output current can be programmed by an
internal 250mV reference.
