Keeping the physical loop areas of AC switching currents as small as possible to reduce radiated emissions.
), instructing engineers on how to calculate required heatsink sizing and layout copper thermal vias to prevent semiconductor thermal runaway. Summary of the Mammano Legacy
Detailed discussion of control methods for power design architectures. Stability and Magnetics (Chapters 6–9):
: The first three chapters establish the basics of power electronics, including definitions of voltage regulation and the selection of essential power components. Keeping the physical loop areas of AC switching
Perhaps the most critical portion of the book is the treatment of feedback and control loops. Borrowing heavily from the Unitrode seminar legacy, Mammano excels in explaining Bode plots, phase margin, and gain margin. He breaks down the differences between voltage-mode and current-mode control with exceptional clarity. The visual approach to understanding compensation networks (Type I, II, and III) allows engineers to visualize how the circuit reacts to load transients, a skill vital for ensuring the stability of the final product.
: In-depth guidance for meeting global regulations for electromagnetic compatibility (EMI) , human safety, and energy efficiency.
. These seminars, which Mammano helped lead for decades, became the "gold standard" for practical engineering education when university curriculums often lacked deep power electronics instruction. Key Highlights of the "Story" A "User Turned Supplier" Stability and Magnetics (Chapters 6–9): : The first
Analysis of basic operating modes.
For applications where the input and output share a common ground, Mammano breaks down the fundamental switching regulators:
Fundamentals of Power Supply Design is an outstanding resource, but it's essential to understand its target audience. It is explicitly designed for: He breaks down the differences between voltage-mode and
, which served as the premier technical resource for engineers worldwide for over 40 years. The Book as a "Trove of Knowledge"
: In-depth analysis of circuit topologies (Buck, Boost, Flyback, etc.) and control algorithms, including voltage-mode vs. current-mode control Magnetics and Feedback : Dedicated chapters on magnetic design
: The foundational step-down converter. Mammano details its continuous conduction mode (CCM) and discontinuous conduction mode (DCM) operations, emphasizing how the duty cycle ( ) governs energy transfer.
