I can provide targeted equations, component sizing workflows, or troubleshooting steps based on these principles.
Robert (Bob) Mammano’s career spans over 50 years in power electronics. His most notable contribution was the design of the in 1974, the world’s first integrated PWM controller IC, which revolutionized switch-mode power supply (SMPS) design by moving from discrete components to integrated silicon.
Arguably the most valuable section for practicing engineers, this part tackles feedback and stability. Mammano explains small-signal modeling, pole-zero plots, and the design of Type II and Type III error amplifiers. Crucially, he introduces the concept of loop gain measurement and compensation without excessive mathematical abstraction, often using Bode plots drawn from real hardware measurements. He also covers modern current-mode control (peak, average, and emulated) and its advantages over voltage-mode control.
Many engineers find magnetics—inductors and transformers—to be the most challenging aspect of power design. Mammano demystifies this topic by treating magnetic design as an iterative, manageable process. Key takeaways from his magnetics chapters include:
No power supply works on paper alone. This section covers component selection (MOSFETs, diodes, capacitors, inductors), gate drive circuits, and—critically—printed circuit board (PCB) layout for low noise and thermal management. Mammano provides rules of thumb for minimizing parasitic inductance, managing ground loops, and placing decoupling capacitors. The inclusion of thermal design (junction-to-ambient, heatsinking, and airflow calculations) rounds out the practical focus.
