Dialog improves LED dimmer compatibility

Dialog Semiconductor has improved its LED light dimming intellectual property. “The first LED driver from this new platform, the iW3688, delivers smooth, flicker and shimmer-free dimming supporting the widest range of phase-cut dimmers. It also eliminates the external bleeder circuit,” said Dialog. Instead of a bleeder circuit (see below) Dialog has integrated digital algorithms that modulate primary FET sw ...
