Description

Dialog Semiconductor’s Power Conversion Business Group leverages years of experience in digital power management to bring to market world class power conversion products for solid state lighting, off-line AC/DC power supplies and LED drivers for display backlighting in consumer electronics. Combining proprietary digital technology with advanced analog and mixed-signal technology, Dialog is leading the way in the next generation of power management.

While typical LED bulbs retain the same harsh white colour as they dim, the dual driver output of the iW3640 lets designers use amber LEDs in parallel with the main white LEDs allowing LED bulbs to gain warmth as they dim. Dialog’s patented, built-in digital dimming technology detects the dimmer type and phase - automatically adjusting LED colour mixing in step with light intensity to provide smooth dimming that closely matches the warmth and ambiance of a traditional dimmable incandescent bulb.
