Other Parts Discussed in Thread: TPS53317

Hello expert,

Customer has a request as below condition. I think TPS51200 is suitable for them but there is no remote sense -- FB+ and FB-. May we know if we have better solution could share with cusotmer? Thanks a lot!!

1. LDO

2. 3V to "1.8V~ 2.4V" IOUT= 3A max.

3. SINK and source capability

4. Feedback Return pin (FB-)

Best regards,

Hi Ann,

What application is it? Why customer need sink/source capability? TPS51200 can support 3A max up to certain voltage, we will need to check if 1.8V~2.4V output is ok.

We don't have other better device with sink/source capability. TPS53317 can support 3A but I don't think it can output 2.4V with 3V input.

Regards,

Weidong

Hi Ann,

We run the test, and it looks TPS51200 will not be able to support 3A output with 1.8V~2.4V output. So it's not a good option for this application.
