On March 2, Dialog Semiconductor announced the launch of two new drive controllers, the iW3629 and iW3631, for high-power (up to 90W) commercial LED lighting applications. In these applications, stroboscopic lighting is important to avoid eye strain, especially when exposed to light sources for extended periods of time. Digital control of Dialog's patented Flickerless technology enables near-zero power-frequency ripple and provides high current stability to eliminate flicker. The iW3629 (non-dimmable) and iW3631 (dimmable) digital power controllers replace up to 45 discrete components, simplifying LED power supply design. Both controllers allow small input and output capacitors, as well as small-sized transformers to optimize performance while reducing power supply size, bill of materials, and cost. These controllers offer power factor (PF) better than 0.95, less than 15% total harmonic distortion (THD) and more than 85% conversion efficiency over a wide load range, easily meeting the requirements of the Design Lights Consortium (DLC)1 . Both controllers feature a two-stage design that supports a wide range of AC inputs (90-277VAC), active startup, and boost circuits for the flyback converter, and the flyback converter provides continuous LEDs. Current. Quasi-resonant control is applied to both boost and flyback conversions to maximize power efficiency. Dialog's Prim Accurate primary side control technology provides excellent line and load regulation without the need for secondary side feedback components. The fast, smooth start is completed in half a second and the PF settling time is very short. The iW3631 dimming controller offers a 1%-100% dimming range with no flicker and no flicker. The controller includes a built-in interface to drive industry-standard 0-10V analog dimmers (thus eliminating the need for external drive sources or microcontrollers), and a dimming interface that supports wireless solid-state lighting applications. Davin Lee, senior vice president and general manager of Power Conversion Business at Dialog, said: "Commercial LED lighting customers have the most demanding requirements for LED lighting performance and reliability. But this market, like the consumer market, is also very price sensitive. So we insist Relentlessly helping customers design lighting solutions that combine state-of-the-art performance with the lowest possible cost. These two new high-power LED driver controllers follow this philosophy and are powered by proven, patented technology. Obvious competitive advantage." The iW3629 and iW3631 are currently undergoing sample trial production and will be available in volume in the second quarter of 2016. Digital controllers for high-power commercial LED lighting applications are on display at Strategies in Light: March 1-3, 2016, Santa Clara Convention Center, Santa Clara, California, USA.
