NXP Semiconductors 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 100 V–120 V and 230 V mains voltages, as well as all power ranges up to 25 W. Based on GreenChip technology, the SSL2108x family has been optimised for non-isolated topologies with high output voltages, and for applications in which compatibility with triac dimmers is not required.
The SSL2108x family offers 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 low electronic bill of materials. The devices also deliver 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.
