摘要：

This paper describes a complete digital controller IC for high-frequency switching converters. Novel architecture and configurations of the key building blocks: A/D converter, compensator and digital pulse-width modulator, are introduced to meet the requirements of tight output voltage regulation, highspeed dynamic response, and programmability without external passive components. The implementation techniques are experimentally verified on a prototype chip that takes less than I mm(2) of silicon area in a standard 0.5 mu digital CMOS process and operates at the switching frequency of I MHz.
