UL51A Overview
UTC UL51A is a high power factor linear constant current LED driver which is applied to LED lighting. Through the distinctive constant current control technology, it realizes that constant current accuracy is less than ±5% and output current is adjustable through external resistor. High power factor and low harmonic distortion are the particular.
