The is a high-performance, single-stage LED lighting power driver IC designed for efficiency and reliability in high-power LED systems. It primarily functions as an isolated primary-side offline regulator, achieving a high power factor by utilizing a proprietary real-current control method. Key Specifications & Features

The LZC8650C operates in QRM, turning on the MOSFET when the drain voltage is at its lowest (valley switching). This minimizes switching noise and improves efficiency. It regulates the output current by calculating the secondary output current using the primary peak current and conduction time information. 3. Key Design Considerations
