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.
