While the book focuses on switching supplies, Mammano begins with the linear regulator—not as a historical footnote, but as a conceptual baseline. He explains dropout voltage, quiescent current, and thermal dissipation using intuitive analogies. He shows why linear supplies are still ideal for low-noise, low-current applications (sensitive RF or audio stages) but catastrophically inefficient for high-current or high-input-to-output voltage differentials.

. It stores energy in the primary magnetizing inductance during the switch ON time and transfers it to the secondary during the OFF time.

: Unlike standard textbooks, it chronicles the history of the power supply industry alongside technical derivations. While the book focuses on switching supplies, Mammano

Mammano guides the reader through Bode plots, phase margins, and gain margins. He maps out how to place poles and zeros in the error amplifier to counteract the power stage's poles, ensuring a high crossover frequency (fast transient response) while maintaining a stable phase margin ( >45∘is greater than 45 raised to the composed with power 5.

For decades, engineers seeking to master this discipline have turned to the work of Robert A. Mammano. His 2017 book, Fundamentals of Power Supply Design , published by Texas Instruments, stands as a definitive blueprint for understanding, designing, and optimizing power conversion systems.

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. Mammano introduces transformer-isolated circuits:

Mammano’s text begins with the absolute fundamentals: managing the transformation of electrical energy from an unregulated source to a regulated output. Power supply design is fundamentally a balancing act between three primary constraints: : Minimizing thermal losses. Size : Maximizing power density. Cost : Ensuring manufacturing viability.

High leakage inductance spikes; large output capacitor ripple. 100 W – 500 W
