Miniaturization of LED drivers with NexGen Vertical GaN™ technology
The brightness and efficacy of LEDs have increased over the years due to innovations in LED technology, resulting in increased efficiency of the LED output and reduced power dissipation. This has also resulted in reduced cooling requirements thus allowing the system designers to use smaller fixtures for lighting luminaires.
The LED driver’s form factor on the other hand has not improved or changed in the last decade. With the current trend of seeking smaller, sleeker, and highly portable consumer electronics and other industrial applications, there’s great demand for miniaturization in the lighting industry for LED drivers to be small. The main roadblock in making them smaller has been the limitations of the power supplies, due to their bulky energy storage components.
By the application of soft-switching topologies, the incorporation of state-of-the-art devices like Vertical GaN technology and combined control, circuits can operate at higher switching frequencies with smaller passive devices, allowing for miniaturized form factors. Read this paper to learn more.
