Popularized largely through the work of Mammano and Unitrode seminars, CMC adds an inner feedback loop. It measures the peak inductor current (or switch current) and uses it as the PWM ramp. The outer voltage loop adjusts the threshold for this current trip point.
While I couldn't locate a specific document or blog post by "Mammano" on the topic, understanding the fundamentals and having access to quality resources can significantly enhance your knowledge and skills in power supply design.

The boost converter steps a lower input voltage up to a higher output voltage. When the switch closes, current flows straight through the inductor to ground, storing energy in its magnetic field while the load is sustained by the output capacitor. When the switch opens, the inductor's voltage flips polarity and stacks on top of the input voltage, forcing current through a diode to charge the output capacitor to a higher potential.

Robert (Bob) Mammano is a pioneer in power electronics with over 50 years of experience. He designed the first integrated PWM controller IC in 1974, fundamentally changing how power supplies were designed. His teaching, compiled in this seminal book, bridges the gap between theoretical knowledge and real-world application, making complex topics accessible to new and experienced engineers alike.
