FP7189 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%.
FP7189 Key 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
