FP7125-LED Driver with Average-Mode Constant Current Control DataSheet
FP7125应用说明 Application Note
General Description 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.
Features Fast Average Current Control Internal 8 to 100V Linear Regulator Linear and PWM Dimming Capability Output Short Circuit Protection with Skip Mode Requires Few External Components for Operation
Applications DC/DC or AC/DC LED Driver Applications LED Street Lighting Back Lighting of Flat Panel Displays General Purpose Constant Current Source Signage and Decorative LED Lighting Chargers
