The LM3445 constant-current controller uses a forward or reverse phase-controller triac to enable offline, uniform, flicker-free dimming of high-brightness LEDs. The device has a 100-to-1 range of ...
This universal triac controller circuit with optocoupler solves the problem that triacs have when functioning at low temperatures (triac needs higher gate current) by adding a transistor at the output ...
Cirrus Logic Inc. introduced a digital LED controller that directly solves dimmer compatibility issues that have been a major barrier to consumer adoption of LED retrofit bulbs. Cirrus Logic Inc.
