Abstract

A dual-mode modular pulse-width-modulator (300) capable of outputting low-speed and high-speed control signals is presented. In one mode, a control signal is generated based on timing parametric data stored in a memory (212). In a second mode, a control signal is generated based on timing parametric data stored in a memory and an external input. Timing parametrics and control variables used to determine the operational mode can be pre-loaded in the memory or loaded through a communication link.
