FP7176 LED Driver with Average-Mode Constant Current Control General Description The FP7176 is an average current mode control LED driver IC operating in a constant off-time mode.
FP7176 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 FP7176 can be powered from an 8.
0 - 450V supply.
A PWM dimming input is provided that accepts an external control TTL compatible signal.
The output current can be programmed by an internal 277mV reference, or controlled externally through a 0 - 1.
5V dimming input.
