Forget lane driving. The Indian road has an unspoken rule: "The horn is not anger; it is a greeting to let you know I am passing."
, authored by Robert A. Mammano , is widely regarded as a definitive resource for engineers and students in the field of power electronics. Drawing from over 40 years of technical seminars conducted by Unitrode and Texas Instruments (TI) , the book consolidates decades of industry-leading expertise into a single, comprehensive guide.

However, some advanced readers note that it is an introductory text. One Amazon reviewer commented, "It is just an ok book. It just goes over the fundamentals," and another felt that other books by authors like Basso or Maniktala are more detailed for experts. This points to its intended audience: it is a foundational reference, perfect for beginners or as a refresher for experienced engineers, but it may not replace a library of advanced, topic-specific texts.

Elias opened his PDF reader to Chapter 3. He pointed to the sections on pulse-width modulation (PWM)—a concept Mammano had practically pioneered. He showed the team how their duty cycles were oscillating wildly. They were forcing energy through the transformer like a firehose through a needle.
is the peak-to-peak inductor ripple current, typically targeted at 20% to 40% of maximum load current).
One of the most praised aspects of the book is its educational approach. A reviewer stated that "this book offers engineers a very readable and practical introduction to power supply design. Mammano presents straightforward explanations on all aspects of design with just enough math and ample illustrations to communicate how power circuits, topologies, and control methods work". The full-color, hardcover format and the use of actual waveform diagrams for key device nodes are also cited as significant positives, helping to demystify complex concepts.

In the world of electronic engineering, the power supply is often the unsung hero. While processors, microcontrollers, and sensors get the glory for "smart" features, none of them function for a millisecond without a clean, stable, and efficient source of power.
Emphasizing the importance of low Equivalent Series Resistance (ESR). High ESR causes internal heating and shortens the lifespan of output filtering capacitors. Drawing from over 40 years of technical seminars
In 1981, Mammano became part of a founding team for Unitrode, where he continued to define industry-leading power control ICs, including the first current-mode controller and the first complete PWM controller in an 8-pin package. He is a named inventor on 13 patents and has contributed numerous papers at technical conferences. However, he may be most renowned for his two-decade-long involvement in the Unitrode/TI Power Supply Design Seminar program, where he prepared topics and presented to engineers worldwide, establishing himself as a respected educator. In recognition of his profound impact, he was the recipient of a Lifetime Achievement Award, and his work as a staff technologist at Texas Instruments helped shape the careers of countless engineers.
In addition to "Fundamentals of Power Supply Design" by Bob Mammano, there are several other resources available for engineers and designers who want to learn about power supply design, including:
