Nexperia 的 LED 驱动器采用含铅或无铅封装

Nexperia NCRxxx LED 驱动器图片Nexperia 的恒流 LED 驱动器为驱动低功率和中功率 LED 提供了极具成本效益且易于实施的解决方案。使用具有较高 P_tot 的封装直接转换为电源电压的较高余量，并联驱动器可用于增大电流能力。

LED 广泛应用于所有细分市场。虽然大功率 LED 需要复杂的驱动器方案，但绝大多数应用都使用电流低于 500 mA 的 LED，并且可以由线性恒流 LED 驱动器驱动。它们易于使用、可靠、经济高效，且不会影响 EMC。

为了驱动高性能 LED，有各种高端解决方案使用升压降压拓扑结构和复杂的控制器，需要深入了解拓扑结构，以创建可靠且符合 EMC 标准的设计。然而，对于低功率和中等功率 LED，使用恒流 LED 驱动器作为简单的线性稳压器，可以实现非常简单和强大的驱动器解决方案。

从功耗方面来看，恒流 LED 驱动器并不理想，但其出色的 EMC 性能、可靠性、简单的实施以及显著降低的系统成本使其成为驱动最高约 500 mA LED 的首选解决方案。Nexperia 节省空间的解决方案是恒流源和汽车应用的理想选择。
