The LZC8650C is an advanced Primary-Side Regulation (PSR) controller optimized for high-power factor (PFC) constant current LED driving. Operating in Boundary Conduction Mode (BCM), it achieves high efficiency, reduced switching losses, and excellent electromagnetic interference (EMI) performance. By eliminating the need for a secondary feedback circuit and an optocoupler, it significantly reduces the bill of materials (BOM) cost and improves overall system reliability. Key Applications High-efficiency LED bulbs and downlights T8/T10 LED tubes External LED driver power supplies Commercial and residential solid-state lighting Technical Specifications and Features Power Dissipation: Approximately 0
The IC senses the output current by monitoring the current flowing in the primary-side transformer winding while sampling the auxiliary winding voltage. It uses this information to infer the output current accurately, eliminating the need for a secondary side sensor. Power Factor Correction (PFC) By eliminating the need for a secondary feedback
: Controls output current accurately using information from the primary side, removing the need for an opto-coupler or secondary feedback components.
: Achieves a high power factor (PF > 0.95) for better energy efficiency .
