LM5175: Unlabeled Currents in Datasheet Equations

Jerry%20Leung

Part Number: LM5175

Hi,

I am working with a client who is looking into using the LM5175 and would like to get some clarifications for the following:

Looking at the datasheet equation (7) and (8) on page 18, can you let me know where 6uA and 5uA respectively from?

Thanks in advance for the help,

Jerry

Hi Jerry,
They are dc offset current. The system owner Vijay is currently on a business trip and he will confirm when returning to office later this week.

Thanks,

Correct. They are offset currents that represent the initial slope when VIN ~ VOUT. These are approximations.
