UCL5811 Overview
The UTC UCL5811 is a single-power stage, isolated and primary side offline LED lighting regulator which achieves high power factor. The proprietary real-current control method can control the LED current accurately from the primary side information. It can significantly simplify the LED lighting system design by eliminating the feedback ponents and the opto-coupler.
