Mammano Robert A 2017 Fundamentals Of Power Supply Design Texas Instruments
The Definitive Guide to Switch-Mode Power Design Published in 2017, by Robert A. Mammano is widely recognized as an indispensable textbook for the power electronics industry. Released through Texas Instruments (TI) , the 352-page volume curates over four decades of collective engineering wisdom. It heavily leverages the iconic technical archives established by the Unitrode and Texas Instruments Power Supply Design Seminars .
: Separate chapters provide in-depth analysis of magnetic design and methods for complying with electromagnetic compatibility (EMI) and safety regulations.
), where he continued to innovate—including creating the first current-mode controller and a landmark PWM controller in an 8-pin package. Retirement to Authorship
The book transitions quickly from inefficient linear regulators—which waste excess voltage as heat—to high-efficiency switch-mode power supplies (SMPS). By utilizing semiconductor switches (MOSFETs or IGBTs) that alternate rapidly between fully ON (low resistance, low voltage drop) and fully OFF (zero current), an SMPS theoretically approaches
Mammano classifies circuit configurations into specific functional categories: Fundamentals of Power Supply Design - IEEE Xplore The Definitive Guide to Switch-Mode Power Design Published
Fundamentals of Power Supply Design , published in 2017 by Texas Instruments (TI), is more than just a textbook; it is the culmination of over 50 years of experience from Robert "Bob" A. Mammano, a seminal figure in the power electronics industry. Widely regarded as the "father of the pulse-width modulation (PWM) controller," Mammano designed the first integrated PWM controller IC in 1974.
totaling approximately 333 pages. It covers the entire lifecycle of power supply design, from foundational theory to practical implementation: Basics & Topologies
No power supply works on paper alone. This section covers component selection (MOSFETs, diodes, capacitors, inductors), gate drive circuits, and—critically—printed circuit board (PCB) layout for low noise and thermal management. Mammano provides rules of thumb for minimizing parasitic inductance, managing ground loops, and placing decoupling capacitors. The inclusion of thermal design (junction-to-ambient, heatsinking, and airflow calculations) rounds out the practical focus.
The book provides in-depth explanations of how power circuits work. It covers essential power topologies, including: Buck and Boost converters. Flyback and Forward converters. Bridge topologies. 3. Control Methods Retirement to Authorship The book transitions quickly from
Mammano emphasizes that . Engineers must systematically weigh the cost of silicon and magnetic size against target system efficiency. For assisted mathematical sizing of these power topologies, engineers frequently pair these principles with modern software like the TI Power Stage Designer Tool . 3. Control Algorithms: Voltage-Mode vs. Current-Mode
A primary challenge highlighted in the text is navigating the complex trade-offs between physical form factor, conversion efficiency, and manufacturing cost. The book begins by transitioning from basic linear voltage regulation to modern high-frequency switch-mode topologies. Non-Isolated vs. Isolated Topologies
Exploring Zero Voltage Switching (ZVS) and Zero Current Switching (ZCS) topologies, such as LLC resonant converters. These architectures eliminate switching losses, allowing engineers to push switching frequencies into the megahertz range while maintaining high efficiency. A Timeless Resource for Power Engineers

efficiency. Mammano establishes that understanding the non-ideal behaviors of these switches is the first step toward master-level design. 2. Power Supply Topologies and Selection Criteria
In the specialized field of power electronics, few names carry as much weight as Robert A. "Bob" Mammano. Widely regarded as the "father of the pulse-width modulation (PWM) controller industry," Mammano co-founded Unitrode Corporation and later contributed extensively to Texas Instruments (TI) after its acquisition. In 2017, he cemented his legacy by compiling decades of expertise into a single, definitive volume: .
. It stores energy in the primary magnetizing inductance during the switch ON time and transfers it to the secondary during the OFF time.
