LM2651开关稳压器提供的高效率超过100:1的负荷范围（1.5A至15mA的）功率转换。 此功能使得在电池供电应用中的需求，同时运行和待机模式电池寿命长LM2651的理想选择。
用于同步整流实现高达97％的效率。 在轻负载时，LM2651进入低功耗迟滞或“休眠”模式，以保持高效率。 在许多应用中，效率在15mA的负载仍超过80％。 一个停机引脚可用于禁用LM2651，降低电源电流小于10μA。
含有专利的LM2651电流模式控制电流检测电路。 此功能消除了外部电流检测电阻其他电流模式DC - DC转换器所需。
该LM2651拥有300 kHz固定频率的内部振荡器。 高振频率允许使用非常小，低调组件使用。
可编程软启动功能可限制浪涌电流在启动时从输入电源，并提供多个电源排序的一种简单方法。
其它保护功能包括电流限制输入欠压锁定，以及过热关机。
