General Description
The FP7182 is an average current mode control LED driver IC operating in a constant off-time
mode.FP7182 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%.

provided that accepts an extemal control TTL compatible signal.The output current can be
programmed by an intemal 250mV reference.or controlled extemally through a 0.2- 1.5V dimming
input.
