FP7125-LED Driver with Average-Mode Constant Current Control DataSheet
FP7125應用說明 Application Note
The FP7125 is an average current mode control LED driver IC operating in a constant off-time mode.
FP7125 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 ±3%.
The FP7125 can be powered from an 8.0 - 100V supply.
PWM & Linear dimming input is provided that accepts an external control TTL compatible signal.
The output current can be programmed by an internal 250mV reference.
