Abstract
An intelligent pulse width modulation (PWM) controller adapts a switch mode power supply (SMPS) system's operating parameters to optimize efficiency, remove hot spots and isolate faults by integrating a microcontroller, PWM digital circuits and analog circuits into a single integrated circuit, thereby reducing the number of external connections, silicon die area and integrated circuit packages. A communications interface is used to communicate with a host system for monitoring operating parameters of the SMPS, e.g., current, voltage, efficiency, operating temperature, diagnostics, etc. In addition, the communications interface may be used to alter the operating parameters (objectives) of the SMPS during operation thereof.
