LNK304 Temperature Variation
Posted by: mk27

Can you please tell us how Vfb and Ifb vary with temperature on the LNK304.
Thank you.

Unfortunately, the information I asked about is not in the Data Sheet.
Most importantly: How can I get information about the affect of temperature on Ifb? What are the limits of this value, over temperature range?
With regard Vfb, although the Data Sheet gives limits, it would be helpful to know specifically how this value is affected by temperature (which direction it moves, approximately how much). However, since I have the limits for this, it is less important than the Vfb information, for which the Data Sheet specifes no min or max over temperature range.
Honestly I tried to find these information these days, but I failed to get them.
Thanks for using PI part.
Vfb varies from 1.54V-1.76v over temperature range -40 to 125 °C, typical value is 1.65V. Unfortunately, Ifb only has variation data at 25 degree, it ranges from 30uA to 68uA. These information can be found at datasheet page 9.
