LYT6068C-TL

LYTSwitch™-6 series family of ICs dramatically simplifies development and manufacturing of off-line LED drivers, particularly those in compact enclosures or with high efficiency requirements. LYTSwitch-6 architecture is revolutionary in that devices incorporate both primary and secondary controllers with sense elements and safety-rated feedback mechanism into single IC. Close component proximity and innovative use of integrated communication link, FluxLink, permit accurate control of a secondary side synchronous rectification MOSFET with quasi-resonant switching of primary integrated high-voltage switch to maintain high efficiency across the entire load range. Incorporates a multi-mode quasi-resonant (QR) / CCM / DCM flyback controller, high-voltage switch, secondary-side control and synchronous rectification driver. Applications include isolated off-line LED driver, smart LED lighting and high-voltage flyback post regulator. UL1577 and TUV (EN60950 and EN62368) safety approved.
