Mammano Robert A 2017 Fundamentals Of Power Supply Design Texas Instruments May 2026

Published in 2017, one might worry the book is dated. On the contrary, its focus on fundamentals ensures its longevity. While silicon processes and packaging have improved (e.g., GaN transistors, integrated power stages), the underlying principles of PWM, inductor volt-second balance, capacitor ripple current, and feedback loop compensation remain unchanged.

Engineers praise the book for:

Mammano famously states: “A perfect schematic is worthless if the PCB layout converts your converter into an oscillator.” This chapter is gold. He discusses:

He includes PCB layout examples—good and bad—from TI’s evaluation modules, showing how a simple 2-layer board can achieve 90%+ efficiency if routed correctly. Published in 2017, one might worry the book is dated

Mammano begins by establishing the fundamental laws governing power conversion, primarily the conservation of energy. The book provides an in-depth analysis of the three primary non-isolated converter topologies, which form the basis for almost all other designs:

The text then expands into isolated topologies necessary for offline power supplies, including:

Robust power-supply design combines topology selection, control theory, component-level choices, thermal and EMI management, and rigorous testing. TI’s 2017 fundamentals provide practical guidance; applying those principles with modern devices (GaN, digital controllers) and careful PCB practice yields reliable, efficient supplies.

Robert A. Mammano’s 2017 book, Fundamentals of Power Supply Design, consolidates over 40 years of engineering expertise from the Unitrode/Texas Instruments Power Supply Design Seminars. The text serves as a foundational guide for new designers and a comprehensive reference for experienced engineers, covering topics from component selection and control topologies to EMI compliance and digital power control.

Eating etiquette: Traditionally eat with right hand, often seated on floor. Many are vegetarian (approx. 30–40% of Hindus; Jains strictly vegan-like). Spices like turmeric, cumin, coriander, and chili are foundational.

Modern trends: Rapid growth of food delivery (Zomato, Swiggy), international cuisines, and organic farming movements.

In the sprawling universe of electronics engineering, the power supply is the silent, indispensable heartbeat. Without clean, stable, and efficient power, the most sophisticated microprocessor or sensor is nothing more than an inert slab of silicon. Among the many texts that attempt to demystify this critical field, one stands out for its clarity, practical rigor, and authoritative lineage: Robert Mammano’s Fundamentals of Power Supply Design, published by Texas Instruments in 2017.

This piece explores the book’s origins, its core content, and why it has become a cornerstone for both aspiring and practicing engineers.

Because the book is published by Texas Instruments, it integrates seamlessly with TI’s portfolio of power management ICs (PMICs), controllers, and MOSFETs.
