AN004 – RCD Snubber Clamp Design for Flyback Converters
This application note provides a practical method for designing an RCD snubber clamp for flyback converters. It derives equations for clamp voltage, leakage-current decay, and snubber power dissipation, then shows how to select the snubber resistor to balance MOSFET voltage stress and clamp loss.
