Infineon presents user-friendly LCC design tool, enabling highly efficient LED driver design

Lighting accounts for a significant portion of the world’s total electricity consumption, emphasizing the importance of energy-efficient solutions in this sector. Power factor correction (PFC) plus LCC resonant topology for constant current output has proven to offer outstanding efficiency combined with a large output voltage range in high-power LED lighting applications, such as outdoor and horticultural lighting. However, the high design effort and complexity have been limiting the widespread usage of this well-suited and efficient topology in LED drivers.

Bridging this gap, Infineon Technologies introduces the LCC design tool, aiming to make a highly efficient yet complex design topology such as PFC plus LCC accessible to a broad LED driver manufacturer community at no additional cost. PFC plus LCC topology is 5 to 6 percent more efficient than other commonly used two-stage topologies. However, the design of LED drivers with this topology is highly time-consuming. Infineon’s LCC tool, which is a novelty in the market, makes the design work much faster and easier.

PFC plus LCC topology is the most favorable version of PFC plus resonant topology due to the wide output voltage range that can be achieved, offering high efficiency of up to 94 percent (more info).
