Product Details

LYTSwitch-6系列ICs显著的家庭simplifies the development and manufacturing of off-line LED drivers, particularly those in compact enclosures or with high efficiency requirements. The LYTSwitch-6 architecture is revolutionary in that the devices incorporate both primary and secondary controllers, with sense elements and a safety-rated feedback mechanism into a single IC.

Close component proximity and innovative use of the integrated communication link, FluxLink, permit accurate control of a secondaryside synchronous rectification MOSFET with Quasi-Resonant switching of primary integrated high-voltage switch to maintain high efficiency across the entire load range.

Product Highlights

Highly Integrated, Compact Footprint

  • Up to 94% efficiency across full load range
  • 在corporates a multi-mode Quasi-Resonant (QR) / CCM flyback controller, high-voltage switch, secondary-side control and synchronous rectification driver
  • 在tegrated 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
