TPS2373-4EVM-758: Inquiry about capacitance of flyback input capacitor in EVM circuit

Part Number: TPS2373-4EVM-758


Hi Team.

For the C28, C68, C69, C30, C31, C32, C33 capacitor at the EVM circuit Is there a limit to the total sum capacity value?

If the sum of the capacitors is large, will not the Hot-swap circuit in the TPS2373-4 affect the fever in the inrush current period?

Thank you.

    Hi Charles,

    If the bulk capacitance (C28 & V62) is too high, then it will be inrush longer (past 81.5 ms, until 90% inrush current) since more current is required to get the bulk cap charged. The other caps are intended for filtering EMI. See section 7.3.5 & 7.4.8 on www.ti.com/.../sluscd1a.pdf

    Can clarify your last sentence? I am unsure what fever means.

    Thanks,
    Tom
