For the working engineer, this book offers a unique mathematical approach:
If you have the first edition, the 2014 update is worth your attention. Key additions include:
Before diving into the PDF, you must understand the author. Sanjaya Maniktala is a former Chief Engineer at Cypress Semiconductor and a technical staff member at Broadcom. He is not an academic locked in a lab; he is a "fixer" who was brought in to solve the world’s most complex switching regulator problems. For the working engineer, this book offers a
It is the book that turns a "circuit assembler" into a "power supply designer."
: It establishes the basic behavior of Buck, Boost, and Buck-Boost converters. He is not an academic locked in a
Maniktala explains why the loop area of the switching node is more important than the width of your traces. He introduces the concept of (AC current loops) vs. "cold loops" (DC current loops). Before reading this book, you might have wondered why your perfectly calculated 1MHz converter was oscillating at 50MHz. After reading it, you will realize that your 2cm return path for the high-frequency diode created an antenna.
The gold standard for ultra-high efficiency. By utilizing Zero Voltage Switching (ZVS), they drastically reduce switching losses at high frequencies. 3. Minimizing Component Stresses and Losses He introduces the concept of (AC current loops) vs
Maniktala’s book is unique because it does not just recite formulas; it teaches you how to negotiate these trade-offs. Unlike the ICS (International Rectifier) or TI application notes that focus on a single topology, this book builds a holistic framework for optimization.
Maniktala dedicates significant real estate to layout. He famously describes the difference between a "quiet" ground and a "noisy" ground. He introduces the concept of (high di/dt loops) and explains why the input capacitor must be placed within millimeters of the switch node. The PDF contains schematics annotated with red "critical paths" that you will not find in a typical datasheet.
