Part Number: TPS54140A

Hi team,

We use this device for Split-rail power supply(Vin=15V, Vout=±12.5V) referenced slva369a. And we plan to add R-C snubber to parallel Voneg side diode to dump out the ringing.

There is two questions.

1. Is it okay the reference the article(e2e.ti.com/.../calculate-an-r-c-snubber-in-seven-steps for Split-rail ? If there are any careful point,please let me know.

2. Is it better snubber add each Vo side?

Best regards,

teritama
