A power supply must remain stable under shifting loads and input voltages. Mammano simplifies control loop theory, teaching engineers how to prevent oscillations while maintaining a fast transient response.
His seminal design, the , introduced in 1974, was the first fully integrated PWM controller IC. This single chip tamed the complexity of switching power supplies, making them smaller, more efficient, and cost-effective for countless applications from computers to spacecraft. A co-founder of Silicon General and later the Power IC division of Unitrode (which was acquired by Texas Instruments), Mammano has over 50 years of hands-on experience in analog power control.
Mammano’s work is distinguished by its "straightforward explanations" and "ample illustrations," using just enough mathematics to explain the behavior of power circuits without becoming abstract.

The book is structured to guide both novice and expert engineers through the complexities of modern power conversion. It is divided into 13 chapters that blend historical perspective with practical design equations. Fundamentals of Power Supply Design - IEEE Xplore
Robert Mammano’s Fundamentals of Power Supply Design remains the "bible" for the practical engineer. It occupies the perfect middle ground between a textbook and a datasheet. It does not just teach you how to calculate component values; it teaches you how to think like a power supply designer. This single chip tamed the complexity of switching
Published in 2017 by Texas Instruments, Fundamentals of Power Supply Design synthesizes over four decades of Mammano’s seminar teachings, application notes, and practical field experience into a comprehensive textbook.
The book consists of 13 comprehensive chapters spanning 81,595 words. Instead of relying solely on heavy theoretical proofs, Mammano presents equations alongside real-world hardware measurements, thermal imaging profiles, and step-by-step design methodologies.

Covers voltage regulation, power components, and the foundational principles of switch-mode power supplies.
The design of a power supply involves a number of key considerations, including:
: From basic buck/boost converters to complex resonant and bridge designs. Component Selection
