The Quest for Efficiency: Deconstructing Sanjaya Maniktala’s Switching Power Supply Design Optimization

• Optimization Rule: An $r$ of approximately 0.3 to 0.4 is typically optimal for buck converters. This minimizes the sum of peak currents (reducing switch stress) and RMS currents (reducing copper loss), without requiring an excessively large inductor size.

Switching Power Supply Design and Optimization, Second Edition

• Target: A Phase Margin of 45° to 60°.
• Optimization: He provides "cookbook" methods for Type II and Type III compensation networks. The optimization goal is to push the bandwidth as high as possible (for better transient response) without encroaching on the switching frequency (which causes jitter) or sacrificing phase margin (which causes ringing).
