UCL5811 Datasheet PSR & PFC LED DRIVER CONTROLLER

Manufacturer: Unisonic Technologies

Overview: UNISONIC TECHNOLOGIES CO., LTD UCL5811 Preliminary PSR & PFC LED DRIVER CONTROLLER CMOS IC.

General Description

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 components and the opto-coupler.

Key Features

  • S.
  • Single stage PFC.
  • Primary side regulation without Secondary Feedback.
  • Quasi Resonance (QR) mode with Fly-back topology.
  • Real-Current control to meet accurate output current.
  • Very less components.
  • Programmable input AC compensation.
  • Leading Edge Blanking on CS/FB pin.
