FP7186-LED Driver with Average-Mode Constant Current Control DataSheet
General Description The FP7186 is an average current mode control LED driver IC operating in a constant off-time mode. FP7186 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 FP7186 can be powered from an 9.0 - 12V supply. A PWM 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 PWM dimming capability Output short circuit protection with skip mode Requires few external components for operation Internal 100V N-MOSFET
Applications DC/DC LED driver applications Back lighting of flat panel displays General purpose constant current source Signage and decorative LED lighting Chargers
