TPS2051B: inrush current control questions

Polly Chung1

Part Number: TPS2051B

Dear team,

May I know if TPS2051B has inrush current control feature? If yes, could you please explain how does it work? I could not find too much detail explanation in datasheet. And what does 3ohms at datasheet's figure 64 mean? Is that figure inrush waveform? Could you please also explain a little bit for figure 64? Thank you.

Regards,

Hi,

3ohm is the load connected to output to make the part current limit.

As with heavy load at output, will lead to inrush current and need some response time to current limit.

For TI's policy, I will first click resolved button.

If you have any other concern, contact me any time.

If you think resolved, please help click'Issue is solved button'.

Thanks.

Dear Ziv,

Thanks for your reply.

Just double confirm, does 3ohms parallel with output?
