NXP Semiconductors today announced three developments in its portfolio of mains connected LED driver solutions: the success of its SSL2101 SSL2101 LED driver IC in matching LED lifetimes in an accelerated lifetime test; the introduction of the SSL 2102 integrated dimmable mains LED driver IC for SSL retrofit lamps and modules; and the launch of its online design tool for SSL applications.
NXP has been conducting the industry’s longest-running test of LED driver ICs, running continuously since December 2008, with zero failures. As of today the test, focused on the SSL2101 SSL2101, the industry’s first integrated dimmable mains LED driver IC, reached 7,000 hours and continues to run, demonstrating that NXP mains LED controller and driver ICs are capable of matching LED lifetimes.
The SSL2102 SSL2102 is the latest addition to NXP’s lighting portfolio, offering deep dimming down to one percent of full light intensity, as well as compatibility with a wide range of dimmers. The SSL2102 SSL2102 is suitable for high-efficiency and high-power factor SSL applications, including SSL retrofit lamps from 8W to 15W; LED modules such as LED spots and down-lights from 15W and 25W; and LED strings for retail display up to a maximum of 25W.
NXP’s new online design tool for SSL applications makes it easy for engineers to evaluate and test the behavior of LED lighting applications based on four NXP products, including the new SSL2102 SSL2102 and SSL2101 SSL2101 for dimmable applications, as well as the SSL1522 and SSL1523 for non-dimmable applications.
The tool enables engineers to quickly select the IC they need and test designs for LED drivers from 2W up to 25W. Two different application types can be created: isolated (flyback) and non-isolated (buck) converters. The tool generates schematic, component and transformer parameters, calculates the design’s efficiency, and presents an overview of efficiency losses.
