He opened the book to Chapter 6 on feedback-loop compensation. "The 'Father of PWM' reminds us that a power supply is just a controlled energy pump. If your loop is too slow, it sags; if it’s too fast, it rings."
Occasionally, TI offers the ebook through their Education Store. As of 2024-2025, they have moved to a "Chapter by Chapter" free model, but corporate bulk licenses exist. Email ti_power_education@ti.com .

Fundamentals of Power Supply Design by Robert Mammano: A Comprehensive Guide
Power supply design is a cornerstone of modern electronics engineering. Every electronic device, from a smartphone to an industrial robot, relies on stable, efficient power conversion. For decades, engineers have turned to the definitive teachings of Robert A. Mammano—a pioneer in the power electronics industry—to understand these core principles. He opened the book to Chapter 6 on
loops small), and shielding to pass regulatory standards (like FCC or CISPR). Finding the "Fundamentals of Power Supply Design" PDF

A perfect schematic will fail if the physical PCB layout allows switching noise to corrupt the sensitive analog feedback paths.
Unlike typical textbooks that jump into heavy math, Mammano explains the , Boost , and Buck-Boost converters using voltage-second balance and charge balance. He introduces the Flyback (the most common low-power topology) and Forward converters with exceptional clarity regarding transformer reset.
The book is slightly showing its age in a few sections. It focuses heavily on traditional silicon MOSFETs and bipolar transistors. There is minimal discussion of wide-bandgap tech (GaN, SiC) which has exploded in the last 5 years. Also, digital power control (PMBus, etc.) gets a brief mention but not the deep dive some engineers need today. That said, the fundamentals of magnetics, control loops, and topology never change—you can apply Mammano’s lessons directly to GaN designs with only minor adjustments.
One of the most challenging aspects of power supply design is the magnetics (inductors and transformers). Mammano simplifies this by explaining core material selection (ferrites vs. iron powder), winding losses (skin effect and proximity effect), and saturation limits. D. Feedback Loop Compensation
