TPS61070: FB Pin Bias Current

Joselito Go

Part Number: TPS61070

Hi Experts,

I see in the datasheet that the typical current to the FB pin is 0.01uA. Do you have any info about what the min and max values for this current might be?

Sorry we don't set max and min for this items. But normally it is about 10nA. You can refer to datasheet to set fb resistor. It should be okay use resistance within recommendation.

Hi Nini,

I have read that section of the datasheet and set the feedback resistor values. Now I am trying to determine how much current I might expect going through the FB pin when it is not "normal", ie across temp. I am interested in this as the amount of current flowing to this pin will directly affect the output voltage. Is there any fb bias current data besides just normal, even if it isn't max and min?

Please advise

Regards,

Josel
