FP7189 LED Driver with Average-Mode Constant Current Control
The FP7189 is an average current mode control LED driver IC operating in a constant off-time mode. FP7189 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 FP7189 can be powered from an 8.0 - 100V 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, or controlled externally through a 0.2 – 1.5V dimming input.
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
