Reconfigurable digitally-controlled low power SMPS

开关模式电源 (SMPS) 是高效的电源处理设备，可为当今几乎所有电子应用提供稳定的电压或电流。在低功耗 (LP) 设备中，工作在几百 kHz 到几 MHz 开关频率下的模拟控制 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电子产品、计算机、照明系统以及消耗功率从几分之一瓦到数百瓦的许多其他设备。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，而在高开关频率下，传统数字系统很难实现这些要求。

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.
