We designed this split +12/-12 power supply board based on the TPS65131 (https://www.digikey.com/en/products/detail/texas-instruments/TPS65131RGER/1672464) a few months ago, but it languished while we worked on some other projects. We had an issue where the negative power rail was unstable. Thankfully, we found a thread that suggested slowing down the VNEG feedback loop (https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/628380/tps65131-q1-abnormal-operation-of-tps65131-q1-s-vneg) with a 51k resistor. We hand-soldered that in, and it worked nicely. Then, the other fix was to flip around the trimmers so the turn direction matched the expected behavior. This should be good to book a second prototype, and then it can go into the shop.
We were chatting with a customer and realized we need a better solution for customers with many solenoids or other high-current on/off loads. This breakout will make it easy to control and power many inductive or high-current loads. An mcp23017
