Specialized chapters on the design and selection of magnetic components like transformers and inductors. Protection and Efficiency (Chapters 10–11):
). Mammano highlights how Zero Voltage Switching (ZVS) mitigates switching losses at elevated frequencies. 3. Magnetics: Inductors and Transformers
Why "Fundamentals of Power Supply Design" is Essential Reading
One of the most valuable sections of the 2017 publication involves magnetism. Magnetic design is frequently cited by engineers as the most "mystical" and difficult part of power supply design. Mammano demystifies inductor and transformer selection, covering core materials, winding techniques, and skin effect considerations. He provides clear formulas for calculating flux density and wire gauge, ensuring the magnetics don't become the bottleneck of the system's efficiency. Specialized chapters on the design and selection of
: Unlike standard textbooks, it chronicles the history of the power supply industry alongside technical derivations.
Comprehensive trade-off analysis between older voltage-mode control and modern peak/average current-mode control.
Fundamentals of Power Supply Design (2017) by Robert A. Mammano remains a cornerstone text for anyone engaged in power electronics. Its blend of historical knowledge from Unitrode and the advanced, modern techniques from Texas Instruments makes it a foundational resource for designing robust, efficient power supplies. 13 Chapters, 333 Pages, Published 2017. Author: Robert A. Mammano. and thermal management. Key Characteristics
There are several common power supply topologies, each with its own advantages and disadvantages. Some of the most common topologies include:
The book's strength lies in grounding complex theory in practical, real-world application. For instance:

Fundamentals of Power Supply Design: Legacy of Robert A. Mammano and Texas Instruments
A power supply is a critical component of any electronic system, responsible for converting AC power from the mains to DC power that can be used by the system's components. The design of a power supply involves a deep understanding of electrical engineering principles, as well as a thorough knowledge of the specific requirements of the system being powered. A well-designed power supply must be efficient, reliable, and able to provide a stable output voltage, while also meeting regulatory requirements for safety and electromagnetic compatibility.

The book’s creation was a deliberate project to preserve this wealth of knowledge, guided by Tim Goodrow of TI. Before publication, Mammano's manuscript was reviewed by TI's top power system engineers, ensuring it met the highest standards of technical rigor and practicality.
