Description

• Parameters: HIGH PFC, HIGH CONSTANT CURRENT ACCURACY, NON-ISOLATED LED LIGHTING DRIVE IC
• Description: SD6920 is designed for non-isolated LED driving with floating Buck structure. With this structure, inductor current is sensed and closed-loop is formed with the internal error amplifier for high constant current accuracy and high input/output regulation rate. Also, high PF in full voltage range is available as its own PFC control. Boundary Conduction mode is adopted for decreasing switching loss and improving the conversion efficiency. SD6920 integrates various protections, such as output open c
• Features: Proprietary constant control method (Patent) Constant current with high accuracy for LED (<±3%) PF>0.9 in full voltage range High conversion efficiency>93% (18W) Boundary-Conduction mode LED short circuit protection (Patent) LED open circuit protection VCC over/under voltage protection Over temperature protection Over current protection
• Applications: Amplifier, LED Lighting, Lighting
