This series of voltage regulators LM2672 is a monolithic integrated circuit manufactured with the LMDMOS process. 这些稳压器提供所有的降压开关(降压)稳压器,可驱动1A负载与出色的线路和负载调节的电流激活功能。 这些器件可在3.3V的固定输出电压,5.0V,12V和可调输出版本。

需要的外部元件数量最少,这些监管机构简单易用,包括专利的内部频率补偿(专利号5382918和5514947),固定频率振荡器,外部关断,软启动,频率同步。

The LM2672 series operates at switching frequency 260 kHz ,从而使小尺寸会比低频率的开关稳压器所需的滤波元件。 由于其极高的效率(> 90%),对印刷电路板的铜线是唯一的散热需要。

一个标准的电感器与LM2672使用家庭可以从几个不同的制造商。 此功能极大地简化了开关式电源供应使用这些先进的集成电路设计。 在数据表中还包括用于二极管和设计工作在开关​​模式电源电容选择指南。

其他功能还包括保证± 1.5输出电压在指定的输入电压和输出负载条件%的容差,并在振荡器频率± 10%。 外部停机包括在内,具有典型的50μA待机电流。 输出开关包括电流限制,以及故障条件下充分保护热关断。

为了简化LM2672降压稳压器的设计过程中,存在电脑设计软件, The LM267X makes it simple Version 6.0
