摘要

本文介绍了一种LED驱动数字控制器的设计与实现。通过利用一个简单的比较器对输出电流进行采样，继电器基控制器的尺寸已经确定。使用5bit DPWM和继电器控制器可以避免低频极限环振荡。

Integrated buck LED driver with application specific digital architecture

This paper describes the design and the implementation of a digital controller for LED driver. By utilizing a simple comparator for sampling the output current a relay base controller has been dimensioned. Using a 5bit DPWM and the relay controller the low frequency limit cycle oscillations can be avoided.
