Dialog Semiconductor plc, a provider of highly integrated power management, AC/DC power conversion, solid state lighting (SSL) and Bluetooth(R) Smart technology, today announced two new driver controllers for high power commercial LED lighting applications up to 90W. In these applications flicker-free operation is essential to avoid eye stress, particularly where there is long-term exposure to the light source. Dialog's patented Flickerless(TM) technology virtually eliminates flicker through digital control that achieves near-zero line frequency ripple.
