Yes. Absolutely.
While silicon carbide (SiC) and gallium nitride (GaN) transistors have emerged since the book’s publication, the physics of optimization remain unchanged. Maniktala’s work on parasitic inductance, thermal vias, and feedback loop compensation applies regardless of whether your switch is Silicon or GaN.
If you are searching for "Switching Power Supply Design Optimization by Sanjaya Maniktala PDF" , you are on the right track to moving beyond "hobbyist" power supply design into professional, reliable, and efficient engineering.
Final Recommendation: Do not settle for a low-quality scan. Purchase the eBook legally through Springer or borrow it via the IEEE Xplore digital library. The clarity of the graphs and the precision of the equations in the official version will save you hundreds of hours of debugging failed prototypes.
Sanjaya Maniktala once wrote: "In power supply design, everything is a trade-off. The engineer’s job is not to avoid losses, but to decide which losses you can live with." This book teaches you exactly how to make those decisions.
While there is no single "draft paper" by this exact name, Sanjaya Maniktala is the author of the authoritative textbook Switching Power Supply Design & Optimization
(McGraw-Hill). The book is widely regarded in the industry for bridging the gap between dense academic theory and practical "hands-on" engineering.
