Robert (Bob) Mammano is a pioneer in power electronics with over 50 years of experience. He designed the first integrated PWM controller IC in 1974, fundamentally changing how power supplies were designed. His teaching, compiled in this seminal book, bridges the gap between theoretical knowledge and real-world application, making complex topics accessible to new and experienced engineers alike.

To illustrate the design of a portable power supply, consider a simple example. Suppose we need to design a power supply for a portable device that requires a 5V, 2A output. The power supply will be powered from a lithium-ion battery with a voltage range of 3.7V to 4.2V. fundamentals of power supply design mammano pdf portable

The book starts with the "why." Mammano explains the physics of heat. A linear regulator (like the LM7805) throws away excess voltage as heat. A switching regulator acts like a high-speed relay, turning fully on and fully off to minimize loss. He provides the foundational equations for efficiency that every engineer must memorize:
) to reduce capacitive noise coupling into nearby traces or the chassis ground. Grounding Strategies Since it’s copyrighted (though often distributed freely by
The design of a power supply involves several fundamental concepts, including:
: The gain at the frequency where the phase shift hits -180∘negative 180 raised to the composed with power should be at least Compensation Networks
In 1981, Mammano became part of the founding team for Unitrode IC Corporation (acquired by Texas Instruments in 1999). At Unitrode, he continued his legacy of innovation, developing the first current-mode controller and other landmark ICs. However, his role as the primary force behind the is what directly led to this book. For over four decades, these seminars became the "go-to" source for the latest in switching-power technology. In 2016, TI tasked Mammano with compiling this vast body of knowledge into a single textbook. The result is a one-of-a-kind resource that serves both as a foundational guide and a practical reference.
Why specifically target a ? Modern engineering workflows are hybrid. You might be at your desk using a simulator (like LTSpice) and simultaneously need Mammano's equation for "Output Ripple Voltage."
