Other Parts Discussed in Thread: TPS54627, TPS54620, TPS54672

Hi Team,

My customer wants to sink 10A for OLED applications; I found TPS54627 can meet 6A continuous current,

My question,

Can we parallel two devices (6A+6A) to meet their current rating, have any confuse if we parallel two devices?

Your any response is appreciated for me

Thank you

I do not show that the TPS54627 is a valid part nmber. Do you mean TPS54620?

Thank you

That is a voltage mode part. You can possibly parallel them but they will not reliably current share. You could parallel TPS54620, but there is a low side current limit for sinking current at 2.3 A, so it will not work for your application.
