UCC28C45: Temperature Characteristic of Start-up Current

masahiko shimizu

Part Number: UCC28C45

Hi,

Could you give me Temperature Characteristic Graph of Start-up Current, please?
If you don't have the data, could you let me know below questions, please?

- How much is typical Start-up Current at 25 degrees?
- When temperature goes to up, Is Start-up Current up or down?

Best regards,
Shimizu

Hi Shimizu-san,

I will need to contact the factory to see if we have this data. This will take a couple of days.

Regards

Peter

Hi Masahiko-san,

The typical start-up current is 72uA to 73 uA. We do not have any information on how this value varies with temperature.

Hi Peter-san,

Thank you for your support.
I add a question, sorry.

At what temp is 100uA of start-up current in datasheet?

Best regards,
Shimizu

Hi Shimizu-san,

There is no way that we can tell. It is a guard banded figure based on the statistical spread of values for this parameter.

Peter
