Dalianda Holding Youshang Launches TI-based LED Smart Lighting Solutions

On June 12, 2014, Dalian General Holdings, a leading Electronic components distributor dedicated to the Asia-Pacific market, announced that its subsidiary Youshang launched a smart lighting solution based on TI’s TPS92314 device.

TI’s TPS92314 device, which is represented by Dalianda Holdings and Youshang, is an off-line controller specially designed with primary-side detection, constant on-time and quasi-resonant switching technology, which can be installed in primary-side regulation and reverse topology. in the LED driver. The TPS92314 application circuit features high power factor (PF), excellent EMI performance and high system efficiency. In addition, the use of TPS92314 device can realize the easy design of application solutions with low external device count, and is favored by more and more designers for its high integration, high efficiency and high reliability.
