TPS54231: Leakage current on pin VSENSE

Norbert Kovács

Part Number: TPS54231

Tool/software:

Is there any maximum (or minimum) input / leakage current value regarding VSENSE? It could affect the precision of output voltage, and I would like to calculate with it.

Thank you in advance,

Norbert

Hi Norbert,

It's mentioned under EA section, 7uA.

Hello, Gautam,

As far as aI understand the 7uA is is the output current of the amplifier (COMP pin) according to the 6th page of datasheet. What I'm interested in is the inverting input of the amplifier (VSENSE pin). It should be in a ~10nA order of magnitude if there isn't any protection diode, but I couldn't find any information about that in the datasheet.

Yes Norbert, you're correct. The sink current for inverting input of EA is ~50nA.
