Hi all, trying to figure out why my charge pump circuit is not working. This is the LTC3260, which has both an inverter and a positive / negative LDO for a dual rail. I'm using it with a 9V battery as Vin, and trying to get +/- 5V regulated lines.
I'm able to get the positive voltage regulated properly, but the output on LDO- shows up as -Vin instead of -5V. I've already tried replacing the chip with a different, fresh one (thinking I might have damaged the regulator), but it has the exact same issue. I also resoldered my circuit to a copy of the same PCB with the same issues. This is a pretty straightforward circuit, so I'm a little bit at wit's end trying to see if I missed something simple!
