Driver IC supports low-cost LED lamps up to 10-W
June 08, 2012 // Paul Buckley
NXP Semiconductors N.V. has introduced the SSL2115x series of high-efficiency GreenChip driver ICs for low-cost LED retrofit lamps.
The new SSL21151 and SSL21153 are designed for non-dimmable 5 W and 10 W LED lamps respectively, providing good current control in flyback and buck-boost configurations. The SSL2115x enables small form-factor LED drivers, using primary-side sensing to regulate current, and offering integrated LED open/short protections, an internal 700 V MOSFET, and a circuit enabling start-up directly from the rectified mains voltage. With the use of an additional valley fill circuit, the SSL2115x series can offer a power factor of approximately 0.9.
“To make LED lamps a viable replacement for incandescent light bulbs on a large scale, many manufacturers are exploring ways to bring the average selling price below the $10 mark. At the same time, the luminous efficacy of LEDs is improving steadily, requiring less power to emit more lumens,” said Ryan Zahn, general manager, lighting solutions product line, NXP Semiconductors. “By offering a compact, low-cost solution for driving LED lamps up to 10W, we are broadening our portfolio of options for lighting manufacturers focused on delivering both energy savings and value to a broad customer base worldwide.”
The new SSL2115x series driver ICs are designed for ultra-low-cost, non-dimmable LEDs using isolated flyback and non-isolated buck-boost topologies, powering up to 5 W (SSL21151) and 10 W (SSL21153), with a small PCB footprint.
Qualification samples of the GreenChip SSL21151 and SSL21153 driver ICs for high-performance non-dimmable LED applications are now available for ordering, with volume production scheduled to begin in July 2012.
