TPS54334: TPS54334 in rush current

Hi,

Basically, the chip has internal 2ms soft-start to minimize inrush current, and you can also refer to CURRENT LIMIT value for both High side and low side switch of Datasheet at page5.

Hi YuChang,

Thanks for your info on how to minimize inrush current.
I supposed the CURRENT LIMIT value you mentioned is the output current.
What I'm keen to know is how much inrush current can this IC Vcc pin sustain? Do you have this information?

Thanks

Hi,

Actually the High-side will detect the Input current as fig7.2 showed, and anyway, I will ask my team brother to double check it.

Hi,

As Yuchang point out, high side has current limit. Not sure what's your concern? When high side on, the current flow through high side is the same with the inductor ramping up current.
