TPS62811-Q1: RC snubber from SW node to GND is needed or not

user4979989

Part Number: TPS62811-Q1

Hi team,

May I know if TPS62811-Q1 need to add RC snubber from SW pin to GND or not?

If snubber can't be used for this device, to reduce SW node spike of TPS62811-Q1, as I know besides input 0402 MLCC decoupling cap, any ways you think we can propose?

Thanks.

Regards,

Allen

Hi Allen,

it is ok to add snubber to reduce, for snubber design, you can refer to http://www.ti.com/lit/an/slua831a/slua831a.pdf
