Hello Billy,
I would recommend the TPS65132L0 or the TPS65132B0. There is a reference design (PMP9781) showing a design example of TPS65132 and OPA1612. Following you have the link to TPS65132 software which goes with the EVM and other useful links…
Florian,
If you haven't had the opportunity already, I would also recommend take a look at our Reference Designs Search Page , where you can search for Reference Designs given a Part Number, Power Design Parameters, etc - and find Reference Designs…
