概览

LM2596 系列降压开关稳压器是单片集成电路，提供了步降（降压）开关稳压器的所有有效功能，能够驱动 3 A 负载，且具有卓越线路和负载调节。这些降压开关稳压器均须极少的外部部件，使用简单，包括了内部频率补偿和固定频率振荡器。LM2596 系列以 150 kHz 开关频率运行，因此比更低频率开关稳压器所需滤波器部件尺寸更小。提供带若干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。适用于 LM2596 系列的标准电感器系列从若干不同制造商提供。此功能大幅简化了开关模式电源的设计。其他功能包括指定输入电压和输出负载条件下保证输出电压的 +/-4% 允差范围，振荡器频率为 +/-15%。包含了外部关断，待机电流为 80 uA。自保护功能包括用于降低输出开关电流限制的两级频率，以及用于故障条件下完整保护的高温关断。参见用于 1.0A 的 LM2595，以及用于 0.5A 的 LM2594。
