Feeling Technology FP7176
The FP7176 is an average current mode control LED driver IC operating in a constant off-time mode. The output LED current accuracy is ±2%. The FP7176 can be powered from an 8.0 - 450V supply.GENERAL DESCRIPTION
FP7176 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%. A PWM dimming input is provided that accepts an external control TTL compatible signal. The output current can be programmed by an internal 277mV reference, or controlled externally through a 0 - 1.5V dimming input.FEATURES
● Fast average current control● Internal 8 to 450V linear regulator
● Programmable constant off-time switching
● Linear and PWM dimming capability
● Output short circuit protection with skip mode
● Requires few external components for operation
