SL8411

产品详情
 
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& Lineardimming input is provided that accepts an external control TTL compatible signal. The output current can be programmed by an internal 250mV reference.
