LYTSwitch-6 Family
Flyback CV/CC LED Driver IC with Integrated
High-Voltage Switch and FluxLink Feedback
Product Highlights
Highly Integrated, Compact Footprint LYTSwitch-6 FB GND BPS V VOUT Primary Switch
and Controller
S 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 D SR SR FET FWD • 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 heat sinks (LYT6079C
and LYT6070C) IS BPP Optional
