Hi Ben,
Here are two more reference designs that I found that I believe are most similar to your requirements.

These are also not exact, but I only have access to the reference designs on…
Hi Derek,
Here is a reference design (www.ti.com/.../pmp9127) I found that is close to your spec. You might want to flip the polarity through the transformer.

Hello Andrew, performance means cost, here some additional silicon cost to drive the synchronous rectifiers. So if you need max. effcy just see Brian's PMP9127, providing >94% effcy for your load range and input range. At min Vin 40V it'll work for 33Vout…
