公司介绍
LM2596降压开关稳压器是单片集成电路,为步降(降压)开关稳压器提供所有主动功能,能够驱动3.0A负载,具备优异的线路和负载调节功能。
这款降压开关稳压器最大程度减少外部组件数量,易于使用,包含内部频率补偿和一个固定频率振荡器。
LM2596系列运行时开关频率150kHz,因此比更低频率开关稳压器所需的滤波器尺寸更小。提供不同引线弯曲选项的标准5 引线TO-220封装,以及5引线D2PAK表面贴装封装。
搭配LM2596使用的标准电感器系列在几家不同电感器制造商均有提供。这一特性大大简化了开关模式电源的设计。
其他特性包括在指定输入电压和输出负载条件下保证输出电压的+/-4%容差范围,振荡器频率容差范围+/-15%。支持外部关断,待机电流80uA(典型值)。自我保护功能包括输出开关的两级频率以降低电流限制和过温关断功能以在故障环境下实现完全保护。查看LM2595的1.0A版本和LM2594的0.5A版本。
