Hello,
I'm using the LM61495 for the first time in a design and I'm running into problems. I have a 100k / 24k9 feedback resistor divider to set the output to 5V. However, the output rises much above the 5V (until the current limiting of the lab supply kicks in). The output follows the input voltage with a little drop of some 300mV. I verified that the resistor divider is actually 100k / 24k9.
Now I wonder if I don't have one of those fixed version installed by mistake. Then the FB voltage is to be connected directly to the output rail without resistor divider. That would explain why the output rises above the set voltage.
The datasheet doesn't seem to tell about the part numbers or package markings of the fixed-version devices. How can I identify those?
Thank you!
