Drive Performance, Maximize Efficiency in 48V Systems with Allegro solutions

Allegro offers a broad array of sensor and power IC products ready for use in the design of 48V systems across a myriad of automotive, industrial, clean energy and data center applications.

Unmatched Energy Efficiency

Reduced Power Loss: By operating at a higher voltage, Allegro's 48V solutions drastically reduce energy loss compared to conventional 12V systems. This translates to a tangible increase in fuel economy for mild hybrids, significantly extends the range for all electrified vehicles and improves energy conversion efficiency in solar inverters.
Higher Power Density: Allegro’s highly integrated 48V solutions enable higher power density space compared to competitive solutions. This translates to further driving range and lowers energy loss in clean energy systems.

Lightweight Design, Enhanced Performance

Weight Reduction and fewer components: The lower current requirements of 48V systems, coupled with Allegro's innovative design approaches, allow for thinner and lighter wiring harnesses and fewer overall components.
Design Flexibility: Allegro's compact and integrated 48V solutions provide engineers with greater flexibility in their designs, enabling the development of more compact solutions without compromising on performance.
