NXP Extends LED Driver ICs for Compact, Non-Dimmable Lamps

NXP Semiconductors N.V. today announced the availability of several new LED driver ICs in its SSL2108x family for compact, non-dimmable retrofit lamps, following the success of the SSL21081. With the addition of the SSL21082, SSL21083 and SSL21084, NXP now provides a single platform for lamp designers developing for 100V – 120V and 230V mains voltages, as well as all power ranges up to 25 W. Based on GreenChip™ technology, the SSL2108x family has been optimized for non-isolated topologies with high output voltages, and for applications in which compatibility with triac dimmers is not required.

Compact, non-dimmable LED lamps are growing in popularity, particularly in markets such as Japan, The SSL2108x family offers a best-in-class solution for these markets, with a high level of efficiency (up to 95% as measured on reference boards); a high level of integration (enabling easy design-in of a full application with only 14 components and a very small PCB area of 18 x 22 mm); and a very low electronic bill of materials (eBoM). The NXP SSL2108x family of devices also delivers tight LED current regulation (better than 5%); a full set of protections, including built-in LED temperature protection via input from an NTC temperature sensor; and an integrated MOSFET.

NXP will showcase the SSL2108x family at Strategies in Light in Santa Clara, California from February 7-9, 2012 (booth 511).

Pricing and Availability:
Indicative pricing is at US $2 per unit for 1,000 pieces
The SSL21081 and SSL21082 are available immediately
The SSL21083 and SSL21084 will be available by the end of February 2012
