A perfectly calculated paper design can fail electromagnetic interference (EMI) compliance if the printed circuit board (PCB) layout is poorly executed. Power supply layout is governed by the management of current loops.

Unlike theoretical textbooks, Mammano’s approach focuses on real-world application:
Most beginners gravitate toward linear regulators (like the 7805) due to their simplicity and low noise. Mammano explains, with elegant graphs, why this fails as current increases. The inefficiency is burned as heat—a 5V/1A supply from a 12V rail wastes 7 Watts. A perfectly calculated paper design can fail electromagnetic
The feedback loop samples the output voltage, compares it to a precise reference voltage, and generates an error signal. This error signal adjusts the PWM controller.
His teachings, often distributed through Unitrode (later Texas Instruments) seminars, are compiled into "The Fundamentals of Power Supply Design"—a must-read for anyone looking to understand the "why" behind the "how." 2. Core Principles of SMPS Design Buy the official eBook today and carry a
This article provides a deep dive into this essential text, covering why it’s a vital, portable resource for modern design and how you can leverage its knowledge for your projects.
It converts the inductor from a dynamic element into a voltage-controlled current source. This simplifies the feedback loop to a single-pole response, making loop compensation much easier while providing inherent pulse-by-pulse current limiting. 5. Magnetics Design and Component Selection
