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…
