This achieved half-cycle resonating branch utilizing inductance coupled inductor. Furthermore...

Synchronous buck converters generate broadband noise typically in 50 – 300 MHz range due to the parasitic LC resonance in the switching loop which consists of input decoupling capacitors, high-side MOSFET and low-side MOSFET. Typically, this parasitic resonance is attenuated using an R-C snubber placed parallel to the low-side MOSFET. However, selection of the R and C value of the snubber is no...
