NXP Semiconductors’ AC-to-DC converter for LED Luminaries. Our latest AC-to-DC converter reference design shows how next-generation LED luminaries can be combined seamlessly with existing electrical infrastructures including wall-mounted dimmers. Based on the NXP STARplug family, it uses robust components and proven technologies to simplify the design of solid-state lighting (SSL) applications.

Solid-state lighting has the potential to offer huge energy savings over conventional lighting solutions. To make the next big step forward in SSL, implementation requires efficient driver solutions that optimize LED lumen output, fit standard luminaire form factors, and are fully compatible with existing electrical infrastructures including wallmounted dimmer switches.

NXP’s AC-to-DC converter reference design for LED luminaries lets you easily design these solutions and optimize lumen output, system lifetime and cost. With just a minimum of additional components, it offers a driver solution that is fully compatible with transistor- or even thyristor (triac)-based wall-mounted dimmers.

Central to this reference design is the Switched Mode Power Supply (SMPS) controller IC TEA1523. This compact flyback converter from our STARplug family guarantees energy efficiency through valley- switching, an adaptive switching frequency, and low resistance internal transistors. Such high efficiency allows the use of lower-specification passive components and smaller heat sinks, translating into lower system costs.

 

FEATURES High energy efficiency at approx. 15W: 85% at 120V AC, 82% at 230V AC Power factor of 0.77 80-270V AC input Output voltage follows VF of the LEDs Output current 1000mA (±5%) Meets safety/isolation regulations (UL 1598 Class 2 and IEC60950) Wide range of built-in protection circuits   BENEFITS Supports the development of next-generation LED luminaries Compatible with existing wall-mounted dimmers Long lifetime solution High energy efficiency Enables fast evaluation and creation of lighting solutions

APPLICATIONS Retrofit LED lamps LED ballasts Signage Contour lighting Commercial lighting e.g. cabinet or freezer lights Other lighting applications
