Deep dive into loop compensation, isolation, and modeling to ensure stability and prevent oscillation.
It is praised for being a "readable and practical introduction," rather than just theoretical, making it perfect for engineers needing to solve problems quickly. Connection to Texas Instruments (TI)
Compared to Abraham I. Pressman’s Switching Power Supply Design , Mammano’s book is more focused, less encyclopedic, and more aligned with modern integrated controllers. Next to Robert W. Erickson’s Fundamentals of Power Electronics (a canonical graduate text), Mammano’s work is less theoretical and more pragmatic, emphasizing rules of thumb and IC-specific implementation. It sits perfectly between a superficial application note and a doctoral thesis. Deep dive into loop compensation, isolation, and modeling
If you are currently designing a power supply, I can provide deeper insight into specific chapters.
No book is perfect. Fundamentals of Power Supply Design is not an exhaustive reference for digital power control (microcontroller-based loops) or resonant topologies like the LLC converter, which receive only introductory treatment. Also, because it was published in 2017, it predates the most recent gallium nitride (GaN) and silicon carbide (SiC) wide-bandgap design practices, though the fundamentals of switching loss and gate drive still apply. The book assumes the reader has basic circuit theory and some familiarity with semiconductors; it is not for absolute beginners with no electronics background. It sits perfectly between a superficial application note
The book extensively covers various topologies (buck, boost, flyback, etc.) and the control methods used for each.
Handles fluctuating battery inputs above or below the regulated output. < 150 Watts Components and Design
Addressing high-frequency parasitic effects, such as the skin effect and proximity effect, which increase copper losses as switching frequencies rise. 4. Feedback Loop Dynamics and Stability
To truly appreciate the book's value, it helps to understand the ingenuity of its author. Mammano didn't invent PWM control in a vacuum. In an interview, he described the development of the SG1524 as something that was "inevitable". Switching power supplies had been built with discrete components since the 1950s, and some individual analog and digital functions were becoming available as separate ICs.
While a diode exhibits a relatively fixed voltage drop (typically 0.3V to 0.7V), a MOSFET acts as a resistor. At high currents, reducing
As the developer of the first PWM controller, Mammano’s insights into control methods are unmatched. The book explains how to implement control loops to achieve stability and efficiency in power management systems. 4. Components and Design
