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. Features
Fast Average Current Control
Internal 8 to 100V Linear Regulator
Linear and PWM Dimming Capability
Output Short Circuit Protection with Skip Mode
Requires Few External Components for Operation Applications
DC/DC or AC/DC LED Driver Applications
