Why Upgrade to 48V? Overcoming the Limitations of 12V Power
The shift to a 48V architecture offers fundamental advantages for any high-power design. By directly addressing the core engineering challenges of power loss, thermal management, and system cost, 48V systems enable a new level of efficiency and performance.
Why Leading Engineers Choose Allegro
Our solutions aren't just 48V-tolerant; they are 48V-optimized. We deliver performance and robustness that adapted 12V components simply cannot match.
Unmatched Robustness for Real-World Transients
Our SG8 technology is based on robust automotive qualified 120V wafer process, provides the critical headroom to withstand harsh 70V-80V transients and ensuring your designs survive the most rigorous transient immunity tests.
Future-Proof, System-Capable Design
Our components are not just supply-capable (able to handle a 48V input); they are system-capable. Many of our ICs operate seamlessly across both 12V and 48V domains, allowing you to integrate Allegro today with confidence that your design is ready for tomorrow's zonal architectures without costly requalification.
