LM27761: input current tolerance

Alan Chang

Part Number: LM27761

Hi,

I'd like to confirm how much tolerance is LM27761 input current, 500mA typical is mentioned on data sheet (7.3,2 input current limit). Do we have min, and max. values? or Is this current limit by what factor, saying temp...?

Hi Alan,

We don't have a min/max value for the current limit. What is the customer VIN condition and the reason they need min/max values for current limit?

Best regards,

Varun

Hi Varun,

customer spec. is +3.3V input then -2.1V output. How does it define OCP?

Hi Alan,

I had a look at characterization data and the max value of current limit for 3.3V input over temperature was 700mA.

Best regards,
