FP7189
FP7189 is LED Driver manufactured by Feeling Technology.
Description
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 pensation 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 patible signal. The output current can be programmed by an internal 250m V reference, or controlled externally through a 0.2
- 1.5V dimming input.
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 ponents for operation
Applications
- DC/DC LED driver applications
- LED street lighting
