的LM2676系列稳压器是单片集成电路，为降压（降压）开关稳压器，能够驱动高达3A的负载具有优良的线路和负载调节特性的积极功能。 High efficiency (> 90%) is obtained by using a low on-resistance DMOS power switch. The series includes fixed output voltage and adjustable output versions of 3.3V, 5V and 12V.

THE SIMPLE SWITCHER CONCEPT PROVIDES A COMPLETE DESIGN USING A MINIMUM NUMBER OF EXTERNAL COMPONENTS. A higher fixed-frequency oscillator (260KHz) allows the use of smaller components. 一个标准电感器使用的LM2676系列是从几个制造商提供，大大简化了设计过程。

LM2676系列还具有内置热关断，电流限制，一个ON / OFF控制输入，可以上下调节功率50μA的低静态电流的待机状态。 The output voltage is guaranteed to a tolerance of ± 2%. The clock frequency is controlled to a tolerance of 11% ±.
