Hi there,
I have a few quick questions about the tl499, which I'm planning to produce 3.3 V, 5V, and 9V in three different circuits from a 3.7 LI-Io battery. There are two input pins for it, a series and switching input. Based on what I wanted in the initial specs, I'm assuming that I'm only supposed to connect my input to the switching input. However, do I leave the series input floating or do I ground it. My next question, is just to check for the application circuit that it is fine to use all the predefined values except for RE2 which will vary based on the desired output voltage. My last question is that in the application schematic, there is an arrow between RE1 and Cp. I assumed that this indicted that RE1 might be a potentiometer but the suggested layout only shows it as a resistor. Therefore, is there any significance to this arrow?
