稳压器

您知道吗？Allegro 现在提供行业内最大的宽输入汽车和工业电源管理 IC 系列之一？

我们的稳压器解决方案提供行业领先的价值 — 以经济的成本实现高质量且有意义的集成。它们还稳健、高效，并可在高温下工作。

我们在自己的 EMC 实验室中测试我们的稳压器解决方案，确保它们满足严格的 EMC 要求，并为我们的客户提供可靠的 EMC 参考设计。

汽车稳压器

我们的独特解决方案可以针对 12V/24V 汽车应用使用 2.8V 至 50V 的输入电压，并生成可为微处理器、收发器、传感器和显示屏供电的输出轨。我们针对安全汽车应用提供经过 ASIL-D 认证的先进 PMIC，从而实现低 FIT 级别系统设计和小尺寸解决方案。单输出稳压器支持各种输出电流功能，其中许多稳压器提供“低 Iq”，从而使保持活动的电源能够将电池输入汲取的电流降至最低。
