Tool/software:

Hi,

We have test TPS51275B Standby current about Iin = 23mA, it higher than other competior Richtek RT6575.

Is any other way to reduce standby current? Thanks!

Hi Jeff,

Are the test conditions different than that mentioned in the datasheet?

Hi Gautam,

No, different with datasheet, our test condition is Ven1=Ven2=3.3V, deivce is enabled, but I can't find this 3.3V/5V both enable condtion standby current on datasheet.

As our test result seems it > 20mA. Is it normal? And if we use TPS51275C can reduce how many standby current, do you have idea for this?

Thanks!

Jeff

Yes it is normal with Ven=3.3V.

It will not reduce.
