Sept. 23--Specialty foundry Tower Semiconductor Ltd. (Nasdaq: TSEM; TASE: TSEM), which markets as TowerJazz, and South Korea'sDMB Technology Ltd. today announced the volume production and shipping of DMB's AC-direct LED driver integrated circuit using Tower's 700V Bipolar-CMOS-DMOS power management process. AC direct LED driver ICs replace AC-DC converters or switched-mode power supply (SMPS) and controls power without the use of large capacitors and inductors over a range of AC input voltages. This enables a constant current IC for supplying current to a load regardless of input voltage variation.
Tower cites a 2013 study by Navigant Research, which says that worldwide unit shipments of LED lamps will grow from 68 million in 2013 to 1.28 billion annually by 2021, and that markets for every other lighting technology will contract over that period.
"LED lighting is a rising market worldwide and Korea is an important region for innovation of this technology. We are very pleased to be an integral player in the Korean market and work with leading-edge partners such as DMB to enable their AC direct LED driver ICs," said Tower Korea president and VP sales Michael Song. "TowerJazz was among the very first foundries to develop a 700V BCD process, and through our collaboration with customers like DMBT, we have achieved volume production with this process and in turn, DMBT has strengthened its market position in the competitive LED lighting market."
