Analytical Modeling and Development of GaN-Based Point of Load Buck Converter with Optimized Reverse Conduction Loss

This work analyzes and develops a point-of-load (PoL) synchronous buck converter using enhancement-mode Gallium Nitride (e-GaN), with emphasis on optimizing reverse conduction loss by using a well-known technique of placing an anti-parallel Schottky diode across the synchronous power device.
