Treatise: "Fundamentals of Power Supply Design" — Mammano & Robert A., Texas Instruments (2017)
Note: I assume you mean the 2017 Texas Instruments materials on power-supply fundamentals by contributors including Robert A. Mammano (or similarly named authors affiliated with TI). The following synthesizes and expands on core themes from TI’s 2017 educational material and standard best practices in modern power-supply engineering.
How to Use This Book in Your Daily Design Workflow
- Problem definition: Identify ( V_in ) range, ( V_out ), ( I_out(max) ), and thermal constraints.
- Topology selection: Use Mammano’s flowcharts in Chapter 3 to choose buck, boost, flyback, or SEPIC.
- Calculate key parameters: Use his step-by-step worksheets for inductor ripple current, output capacitor ripple voltage, and FET power loss.
- Simulate: While the book predates some AI tools, it suggests using TI’s WEBENCH Power Designer (a free online tool) as a companion.
- Prototype layout: Follow the layout checklist from Chapter 8—Kelvin sense, loop area reduction, thermal relief.
- Test: Measure efficiency, load transient, and Bode plot. Compare results to his empirical “smoke test” advice.
6. Thermal, layout, and packaging
- Thermal management: estimate junction temperatures (Tj = Ta + Pd·θJA), derate parts under worst-case ambient and reduced convection, use heatsinks or copper pours as needed.
- PCB layout rules: short high di/dt loops, separate power and control grounds with star or split-ground strategy, place input/output caps close to switch node and device pins, keep sensitive feedback traces away from noisy nodes, route return paths on continuous ground planes.
- Switch-node considerations: minimize trace length and loop area to reduce EMI; use snubbers or RC damping where necessary.
Conclusion: The Engineer’s Desk Reference
Robert Mammano’s Fundamentals of Power Supply Design (2017, Texas Instruments) is more than a book—it is a transfer of wisdom from a master to the next generation. For the student, it provides a clear on-ramp to a challenging field. For the practicing engineer, it is a trusted desk reference to resolve a stability issue, select an inductor, or sanity-check a loop compensation network.
In an era of automated design tools and AI-generated schematics, Mammano’s voice reminds us that great power supply design still requires fundamental understanding. If you design electronics that plug into a wall or run on a battery, this book belongs within arm’s reach.
Final Verdict: Essential reading for any hardware engineer. Five stars for clarity, authority, and practicality.
In 2017, Robert A. Mammano—widely celebrated as the "Father of the Pulse Width Modulation (PWM) controller industry"—released a definitive text titled Fundamentals of Power Supply Design. Published in collaboration with Texas Instruments, this 333-page hardcover serves as a technical compendium of four decades of knowledge gleaned from the legendary Unitrode/TI Power Supply Design Seminars. The Author: A Legacy in Silicon
Robert (Bob) Mammano’s career spans over 50 years in power electronics. His most notable contribution was the design of the SG1524 in 1974, the world’s first integrated PWM controller IC, which revolutionized switch-mode power supply (SMPS) design by moving from discrete components to integrated silicon.
Mammano co-founded Unitrode Corporation in 1981, which was later acquired by Texas Instruments in 1999. As a TI Fellow, Mammano was instrumental in developing the Power Supply Design Seminars (PSDS), which have educated over 50,000 engineers globally since 1977.

Robert A. Mammano’s Fundamentals of Power Supply Design , published by Texas Instruments in 2017, is a comprehensive technical resource for engineers, based on 40 years of Unitrode/TI Power Supply Design Seminars. Mammano, widely considered the "father of the PWM controller," designed the first integrated PWM controller IC (the SG1524) in 1974. Core Technical Structure
The 333-page book is organized into 13 chapters that move from foundational electronics to advanced system integration:
Foundations & Components: The first three chapters establish the basics of power electronics, including definitions of voltage regulation and the selection of essential power components.
Topology Selection: Chapter 4 focuses on choosing between hundreds of circuit topologies based on cost, size, and efficiency trade-offs. Problem definition: Identify ( V_in ) range, (
Control Algorithms: Chapter 5 covers methods for controlling switching, which is essential for designers unfamiliar with advanced control algorithms.
Stability & Compensation: Chapter 6 addresses feedback-loop modeling and compensation to ensure the power supply remains stable and does not become an oscillator.
Magnetics & EMI: Separate chapters provide in-depth analysis of magnetic design and methods for complying with electromagnetic compatibility (EMI) and safety regulations.
Advanced & Digital Control: Later chapters discuss fault management, high-efficiency standards, and the growing value proposition for digital control.
Construction & Layout: The final chapter, authored by Robert Kollman, provides practical tips on PCB layout, grounding techniques, and thermal management. Practical Value for Designers
Digestible Math: Reviews note the book uses "just enough math" alongside ample illustrations to explain complex subdisciplines. forward voltage drops in diodes
Historical Context: Each chapter (except the first) includes references to original TI/Unitrode seminar papers, connecting modern design to decades of industry-standard research.
Regulatory Compliance: It provides detailed guidance on meeting global standards for human safety and energy efficiency. Fundamentals of Power Supply Design: Robert A. Mammano
Strengths and Distinctions
- Readability: The book is written in a clear, conversational tone. It assumes the reader is intelligent but perhaps inexperienced in power design, avoiding unnecessary jargon without dumbing down the physics.
- Visual Aids: Texas Instruments publications are known for high-quality graphics, and this book is no exception. The diagrams of current flows, magnetic fields, and Bode plots are instrumental in conceptualizing the text.
- Real-World Component Focus: The text constantly reminds the reader of parasitic elements—ESR in capacitors, forward voltage drops in diodes, and switching losses in MOSFETs. This distinguishes it from university textbooks that often rely on "ideal" component models.
Criticisms and Complementary Resources
No book is perfect. Some readers note that the book assumes a basic understanding of circuit theory (Ohm’s law, impedance, diodes, transistors). It is not for absolute beginners. Additionally, it touches only lightly on digital power management (PMBus, I2C-controlled converters) and does not deeply explore resonant or soft-switching topologies.
For those topics, TI’s application notes (many written by Mammano himself) and online training videos are excellent companions.
7. Efficiency Metrics and Modern Challenges
The 2017 edition looks toward the future. Mammano dedicates an entire chapter to light-load efficiency: the rise of pulse-frequency modulation (PFM) and burst mode to reduce quiescent current in battery-powered devices. He also introduces the concept of Dickson charge pumps for low-current, low-noise step-up/down.
