General Description
The FP7181is an average current mode control LED driver IC operating in a constant off-time
mode.FP7181does 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 FP7181can be powered from an 8.0- 100V supply.A PWM & linear dimming input is
TTL compatible signal.The output current can be
provided that accepts an extemal
