Allegro Regulators for Industrial Applications
Today’s advanced Industrial Systems demand robustness, efficiency, and high performance.
Allegro offers a broad portfolio of highly integrated multi-output regulator ICs, rated and qualified to high temperature conditions.
We also go beyond the industry-standard practices of IC testing and Evaluation Board support, making investments in real-world simulations through input transient testing as well as evaluating reference designs in our EMC labs.
