Maximum Vout of LT8609S

Hello,

Would you let me know the  maximum Vout voltage of  LT8609S?

My customer requests this spec. of LT8609S.

It seems to be under 42V, but I can not find the exact spec. in LT8009S datasheet.

Please let me know.

Regards,

Se-woong

    Hello,

    the maximum VOUT of LT8609S is just a function of VIN and can be differenciated for the two operating modes:

    1. Dropout. Please check these two diagrams from the datasheet:

    2. In 'regular' operation the maximum duytcycle (dependent on frequency and min off time) defines the maximum Vout.

    In general, as any other buck reguator Vout is always smaller than VIN, hence the absmax on Vin somewhat dictates the maximum achievable Vout as well.

    kind regards
