Figure 1: A passive primary clamp RCD solution (highlighted) is highly dissipative and limits the efficiency and operating frequency of flyback power supplies

Off-line flyback power supplies require a clamp circuit (sometimes called a snubber) on the primary side of the transformer to limit the drain-source voltage stress on the power MOSFET when this switch turns off during normal operation. There are several approaches to designing these clamp circuits. Low-cost pa
