A power supply must maintain a stable output voltage despite rapid changes in load current or input voltage. Fundamentals of Power Supply Design dedicates significant real estate to control theory and loop compensation. Voltage Mode vs. Current Mode Control Mammano compares the two primary control philosophies:
As a handy reference for formulas and complex real-world trade-offs.
. It stores energy in the primary magnetizing inductance during the switch ON time and transfers it to the secondary during the OFF time. A power supply must maintain a stable output
For decades, power electronics engineers relied on the application notes and seminar books distributed at Unitrode's annual educational programs. When Texas Instruments acquired Unitrode Corporation in 1999, they preserved and expanded this educational legacy.
Continuous input current, ideal for Power Factor Correction (PFC). Output current is pulsing; prone to short-circuit damage. Non-Isolated Current Mode Control Mammano compares the two primary

The book systematically breaks down the complex multi-disciplinary nature of power supply design into manageable technical segments. 1. Power Supply Topologies For decades, power electronics engineers relied on the
Later chapters explore the growing importance of digital control methods in modern power systems.
Texas Instruments/Unitrode technology collection.
For anyone looking to master the design of Buck, Boost, or Flyback converters, or simply trying to understand how to stabilize a control loop, this book is a highly recommended investment.
Non-isolated DC-DC converters are used when the input and output share a common ground. Mammano covers the three fundamental switching regulators:
