LTC7803 ITH pin

[Flyback]

Hi,
Pg 3 of ltc7803 datasheet appears to suggest that the regulation range of the ITH pin is only 0.6 to 1.2v

Do you know why the range is so narrow?

I wouldn't really call it a regulation range, more an operational range.

It's almost an internal connection, as it appears to be designed to be connected via passive components to ground.

ABSOLUTE MAXIMUM RATING is –0.3V to 2V.
