TPS552892-Q1: MODE pin current

Weixu Pan

Part Number: TPS552892-Q1

Tool/software:

Hi Team,

I would like to inquire MODE pin's max sink/source current to do the worse case analysis.

I don't find it in the datasheet.

Could you please help to provide it?

Hi Weixu,

Thanks for reaching out.

The Mode pin is voltage detection pin for PFM/FPWM mode selection, may I know why the pin's current is needed for WCCA?

BRs,

Bryce

Hi Bryce,

I connected a 0 ohm to GND for this pin in our design.

It need to estimate the current through the resistor.

I think it will be provided by the pin.

Could you help check if it is correct?

Hi Weixu,

The leakage current is about nA level. But we don't have the exact value for this. Hope it helps.

BRs,

Bryce

Hi Bryce,

So the value would not exceed uA level, right?

Hi Weixu,

Yes, it will not exceed uA level.
