FP7186-LED Driver with Average-Mode Constant Current Control DataSheet
The FP7186 is an average current mode control LED driver IC operating in a constant off-time mode. FP7186 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 FP7186 can be powered from an 9.0 - 12V supply. A PWM dimming input is provided that accepts an external control TTL compatible signal. The output current can be programmed by an internal 250mV reference.
