监管者的LM22680系列单片机提供了一个降压的积极作用（降压）开关稳压器驱动高达2A的优秀的线路和负载调节特性负载能力的所有集成电路。 High efficiency ("90%) is achieved through the use of N-channel MOSFETs with low resistance.

In simple switches ® The concept provides an easy-to-use complete design using a minimum number of external components and state the WEBENCH ® Design tools. WEBENCH of National Semiconductor ® Tools include functions for external component calculation, electrical simulation, thermal simulation, etc., and build-IT boards for easy design. The clock switching frequency is made up of an internal fixed frequency oscillator that operates at 500 kHz. 其开关频率也可通过一个外部电阻调整或同步至外部时钟高达1MHz。 它也可以自动同步操作多个监管机构共享相同的开关频率。 该LM22680系列还具有内置热关机，电流限制和使能控制输入，可以关闭电源稳压器以低25μA的静态电流待机状态。 An adjustable soft-start function provides the selection of an appropriate external soft-start capacitor.
