TPS54239: TPS54239E maximal output capacitor

Part Number: TPS54239

Hello,

I'm using TPS54239E in a new design.

For a 5V output voltage, the maximum output capacitor total value is 68µF (table 1 of datasheet).

- Does this maximal value includes DC bais effect of the capacitor?

- Does this value inclued  input capacitor of the load where TPS54239 dc/dc converter is connected?

In my schematic, output  of TPS54239E is connected on 3 secondarys DC/DC converters.

One of this secondarys converter are a 1.6 inch away from the TPS54239E converter.

The two others secondarys converters are a 0.3 inch away from the TPS54239E converter.

I need to know if input capacitors of secondarys dc/dc converters should be inclued (or not) in the total output capacitor of TPS54239E.
