Part Number: TPS2121

Hello,

Our customer has an question for TPS2121.
The datasheet defines only TYP value for t_FSW as 5us.
Could you please tell me the max value for it?

 

Regards,
Oba

    Hi Oba,

    We do not spec the max or minimum value for any timing. This is because timing is a very sensitive parameter which can be affected by supply slew rate, tail stability, output load and load nature(capacitive, inductive, etc).

    5us is the typical switchover time for fast switching in TPS2121. Please refer to Section 9.3.7 for a more information on fast switchover.
