• Switching Power Supply Design, 2nd Ed. by Abraham I. Pressman. This is a fairly painless introduction that covers the basics from the Buck & Boost topologies, to Push-Pull, Half&Full Bridge, Flyback. Transformer design for each type is discussed. There is also one chapter on transformer design by itself. Other  Miscellaneous topics applicable to SMPS are also discussed, including a little bit on RCD snubbers. There is also a section that shows many waveforms associated with different SMPS topologies, taken from an oscilloscope. A great tool for debugging your first SMPS
• Switchmode Power Supply Handbook by Keith Billings. This is a much more advanced book. It discussed the same basic concepts, but at a much more technical level.
