LYTSwitch-6 Family
Flyback CV/CC LED Driver IC with Integrated High-Voltage Switch and FluxLink Feedback
Product Highlights
Highly Integrated, Compact Footprint
Up to 94% efficiency across full load range Incorporates a multi-mode Quasi-Resonant (QR) / CCM / DCM flyback
controller, high-voltage switch, secondary-side control and synchronous rectification driver Integrated FluxLink™, HIPOT-isolated, feedback link Exceptional CV/CC accuracy, independent of transformer design or external components Adjustable accurate output current sense using external sense resistor PowiGaN™ technology – up to 100 W without heatsinks (LYT6079C and LYT6070C)
EcoSmart™ – Energy Efficient
Less than 30 mW no-load including line sense (without PF front end) Designs using LYTSwitch-6 easily meet Energy Star and all global
lighting energy efficiency regulations Low heat dissipation
