Mammano Robert A 2017 Fundamentals Of Power Supply Design Texas — Instruments [upd]
The text is organized into 13 chapters covering the full lifecycle of power supply development:
An efficient power stage is useless without a robust control loop to keep the output voltage stable during line and load transients. Having invented the SG1524 (the world's first integrated PWM controller IC), Mammano's insights into feedback loops are unparalleled. Voltage Mode vs. Current Mode Control
Mammano candidly discusses what can go wrong: inrush current, reverse recovery of body diodes, subharmonic oscillation in current-mode control, and transformer saturation. This “failure analysis” mindset prepares the engineer for debugging hardware, not just simulating ideal circuits.
As the pioneer of PWM controllers, Mammano provides unparalleled depth on control methods.
If you are interested in applying these principles, you can explore the Texas Instruments Power Stage Designer tool which complements the design concepts discussed in the book. The text is organized into 13 chapters covering
Steps voltage up. It features continuous input current, making it ideal for Power Factor Correction (ROI) front-ends.
Are you experiencing any specific bottlenecks like or magnetic saturation ?
If you are looking to deepen your understanding of power supply design, this book is highly recommended as a go-to reference.
Selecting the optimal switching network is the most critical architecture choice an engineer makes. Mammano systematically evaluates the standard converter topologies based on efficiency, voltage stress, and target application power levels: Isolation Requirement Power Range Primary Benefit / Target Industry Non-Isolated < 100 Watts Current Mode Control Mammano candidly discusses what can

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
Power-supply design translates system requirements into a stable, efficient, safe, and cost-effective source of energy for electronics. TI’s 2017 fundamentals emphasize practical engineering trade-offs: topology choice, converter control, component selection, thermal and EMI management, and verification.
Non-isolated DC-DC converters are used when the input and output share a common ground. Mammano covers the three fundamental switching regulators: If you are interested in applying these principles,
A primary challenge highlighted in the text is navigating the complex trade-offs between physical form factor, conversion efficiency, and manufacturing cost. The book begins by transitioning from basic linear voltage regulation to modern high-frequency switch-mode topologies. Non-Isolated vs. Isolated Topologies
Treating the switching regulator as a continuous linear system to analyze its frequency response.
Each topology is explained with block diagrams, timing waveforms, and design equations.
Mammano stresses that a perfect schematic can fail utterly with poor PCB layout. He provides golden rules: keep power loops short, separate analog and power grounds (Kelvin connections), place decoupling capacitors correctly, and manage heat sinks and airflow.
