bright idea dimmable luminaires
latest AC/DC converter reference design shows next-generation luminaires combined seamlessly with existing electrical infrastructures including wall-mounted dimmers. Based STARplug family, uses robust components proven technologies simplify design solid-state lighting (SSL) applications.
features High energy efficiency approx. Power factor 0.77 input Output voltage follows LEDs Output current 1000 Meets safety isolations regulations 1598 Class IEC60950) Wide range built-in protection circuits benefits Supports development next-generation luminaires Compatible with existing wall-mounted dimmers Long lifetime solution High energy efficiency Enables fast evaluation creation lighting solutions applications Retro-fit lamps ballasts Signage Contour lighting Commercial lighting e.g. cabinet freezer lights Other lighting applications
Solid-state lighting potential offer huge energy savings over conventional lighting solutions. make next step forward implementation requires efficient driver solutions that optimize lumen output, standard luminaire form factors fully compatible with existing electrical infrastructures including wall-mounted dimmer switches. Semiconductors' AC/DC converter reference design luminaires lets easily design these solutions optimize lumen output, system lifetime cost. With just minimum additional components, offers driver solution that fully compatible with transistor even thyristor (triac) based wall-mounted dimmers.
Central this reference design Switched Mode Power Supply (SMPS) controller SSL1523. This compact flyback converter from STARplug+ family guarantees energy efficiency through valley switching, adaptive switching frequency low-resistance internal transistors. Such high efficiency allows lower-specification passive components smaller heat sinks, translating into lower system costs. full suite built-in protection features include, cycle cycle adjustable, over-current protection (OCP), under voltage lock-out (UVLO), over voltage protection (OVP), over temperature protection (OTP), short winding protection (SWP) demagnetization protection. design also enables easier thermal management hence better lumen consistency longer lifetimes, with system lifetime further enhanced through limited electrolytic capacitor requirements.
reference design used wide variety applications. Tailored single state-of the-art, LED, other LEDs combinations implemented easily. STARplug+ SMPS control SSL1523 low-power systems Integrated MOSFET (RDS(on) Highly efficient power conversion RDS(on) reduces switching losses Adaptive switching frequency Valley switching
