LTC3616 compensation

Category: Hardware
Product Number: LTC3616EUDD#PBF

We are using the LTC3616. On our prototype, we have left the compensation pin ITH unconnected. We still get pretty good performance but to enable internal compensation, we should have connected it to SVIN. What effect does it have to leave it unconnected? Is there predictable behaviour? The issue is can we release prototype product to customers or might something unexpected occur, risking business? Therefore we should tie it to SVIN before release.

You should connect it to SVIN. There are a lot of factors that might affect the converter's performance in other places. Leaving it open makes your converter uncompensated. Since you are releasing a prototype, I suggest having an option to tie to SVIN (through a 0-ohm resistor) as well as having an external component compensation.
