LM5030: Snubber design at the secondary side of transformer in Push Pull Dc to Dc converter design using LM5030

DEEPAK V14

Part Number: LM5030

Hi,

I have got some idea about how to design snubbers for Push Pull MOSFET available at the primary side of the transformer.

But I am unable to get any application notes that can guide to design Snubber at the secondary side of the transformer for protecting the Schottky diodes.
Anyone, Please help...

Thanks and Regards

Hi Deepak,

This is the general guideline I typically follow for tuning snubber values:

Power Tips: Calculate an R-C snubber in seven steps

Ringing in switching power supplies can generate radiated and conducted noise, create circuit jitter and excessive dissipation, and easily overstress components. Ringing is a major concern in applications…

Hi,

Once again thanks Ben Lough.
Theses tips are easy to understand and hence much helpful in identifying the suitable snubber values.
