Switch-mode power supplies (SMPS) are highly efficient power processing devices providing regulated voltage or current for virtually all electronic applications today. In low-power (LP) devices analog-controlled SMPS operating at switching frequencies between several hundreds of kHz and several MHz have been preferred to more flexible and intelligent digital-controlled solutions. Applications include portable and consumer electronics, computers, lighting system, and numerous other devices consuming power from a fraction to several hundreds of watts. The prevalence of the analog designs comes from the requirements for a fast controller action and simple implementation that, at the high switching frequencies, are challenging to achieve with conventional digital systems.

开关电源（SMPS）是一种高效的电源处理设备，为当今几乎所有的电子应用提供可调节的电压或电流。在低功耗（LP）器件中，在数百kHz和几MHz之间切换频率下工作的模拟控制SMPS比更灵活和智能的数字控制解决方案更受青睐。应用包括便携式和消费类电子产品、计算机、照明系统和许多其他消耗功率从零头到几百瓦的设备。模拟设计的流行源于对快速控制器动作和简单实现的要求，在高开关频率下，这是传统数字系统难以实现的。
