摘要:
A digitally compensated circuit for a power supply having a plurality of integrated circuits. The plurality of integrated circuits has a digitally variable slope controller to adjust charge time of an inductor and voltage distortion and an adjustable voltage generator, which generates a modified voltage set point. The digitally compensated circuit has a comparator, which compares the modified voltage set point to a first feedback and turns off a comparator output signal when first feedback approaches or exceeds the modified voltage set point. An adjustable pulse width modulator generator produces an output voltage. A current monitor receives output voltage and provides a second feedback, which is transferred to the plurality of integrated circuits. An inductor receives output voltage and generates variable output power for a load, utilizing the digitally variable slope controller to reduce oscillation, system disturbances, and subharmonic oscillations over a dynamic voltage input range.
