Other Parts Discussed in Thread: TPS54295, TPS54528

Hi all

Would you mind if we ask TPS54295 and TPS54528?
How much is VREG5 when Vin is less than 5V? Will it be 5V?
(VREG5 is typ 5.5V in case of 6 V < VIN < 18 V)

We need your help always.

Kind regards,

I do not support those parts directly, but if Vin is lower than 6 to18 V then VREG5 will be lower also. VREG5 is derived from an LDO. So long as VREG5 is above teh UVLO it will be ok.
