Description
General part information
IW3989 Series
The iW3989 AC direct LED driver offers a high-performance, low BOM cost approach for phase-cut dimming SSL LED driver applications by integrating a high-voltage MOSFET and eliminating the need for magnetics, an RC damper and an external bleeder. Ideal for downlights and replacement bulbs such as GU10, PAR, A19, and BR types, the device can operate with virtually all dimmer types including leading-edge, trailing-edge and smart dimmers, while providing a very fast dimmer transient response.
The iW3989 achieves efficiency similar to a switch-mode converter without utilizing magnetics for energy storage, which addresses the thermal challenges of SSL lighting without adding unnecessary cost. And by removing the magnetic component, there is no audible noise when interfacing with a TRIAC dimmer, providing a noise-free, flicker-free and robust solution that approaches the feel of an incandescent lighting experience.
