LEDs while minimizing precious board space

The light emitting surface of the CST-90 is a single, monolithic die that is nine square millimeters in size and integrates seamlessly with industry standard optics. The CST-90 produces 1,000 lumens with 10 watts input and 2,750 lumens at its maximum rated drive current. PhlatLight LEDs are mercury-free and highly reliable and have a lifetime of 60,000 hours with lumen maintenance of greater than 70 percent. The CST-90 is ideally suited for general lighting applications, including architectural, retail and residential lighting as well as wide area street and parking lot lighting.

The NXP SSL2101 is a small form factor Switched Mode Power Supply (SMPS) controller IC specifically designed to drive LED devices and provide dimming capabilities to further improve the energy efficiency of LED lighting. The SSL2101 can drive lighting systems with variable power requirements which include LED retro-fit lamps, LED modules, LED spots, down-lights and LED strings for retail displays.The dimming capabilities offered by the SSL2101 create unique opportunities for lighting system designers to produce more energy efficient systems. With the high integration level, this cost effective device reduces the total electronic components and allows designers to fully reap the benefits of dimmable LEDs while minimizing precious board space.

Meeting the constantly evolving lighting needs and supporting the green lighting revolution, NXP’s solutions help to deliver lighting products with improved efficiency,” said Robert de Jonge, director of marketing for power & lighting solutions, NXP Semiconductors. ”The SSL2101 enables products to have lower energy consumption, longer lifetimes, smaller form factors and increased robustness.The SSL2101 is fully compatible with today’s lighting infrastructure and can operate directly from rectified mains power supply in combination with a phase cut dimmer. The SSL2101 includes a high-voltage power switch and can start-up directly from the rectified mains voltage, so no external startup circuit is required. To support its dimming capabilities the SSL2101 contains two integrated high voltage-switches for bleeder operation and an input that can be used to sense lamp power usage and activate additional bleeder action when needed.
