的LM2679系列稳压器是单片集成电路,提供降压开关稳压器能够驾驶出色的线路和负载调节特性5A负载(降压)所有的积极功能。 高效率(> 90%)获得通过使用低导通电阻DMOS功率开关。 该系列包括3.3V,5V和12V的固定输出电压和可调输出版本。

SIMPLE SWITCHER的概念提供了一个完整的设计,使用最少的外部元件数量。 一个较高的固定频率振荡器(260KHz),允许使用体积更小尺寸元件。 一个标准电感器使用的LM2679系列是从几个制造商提供,大大简化了设计过程。

其他功能还包括加入一个软启动时序电容逐步打开稳压器在上电时的输入浪涌电流的能力降低。 LM2679系列还具有内置热关断和电阻可编程电流限制保护设备和负载电路故障条件下的功率MOSFET开关。 输出电压是保证一个公差± 2%。 时钟频率控制在公差± 11%。
