TPS50601A-SP: REFCAP Capacitor

Part Number: TPS50601A-SP

The datasheet says 470nF required on the REFCAP pin. Is this a minimum value? Would it be ok to have 1uF?

-Reasoning is to reduce BoM line items. I am using a 1uF cap elsewhere in the design.

Thanks,

Hey James,

Our analysis for the stability of the internal rail was done with a 470 nF cap.
While it may be stable with 1 uF, we dont do our testing with anything other than 470 nF.

Thanks,
Daniel
