I currently use the UCC28610 in a 16.5V 45W module, and was hoping to use the same controller for a new multiple-output module I am designing, with +60/+20/0/-20/-60 rails and a total 42W output power.
However, I notice that on some of the TI design tools the UCC28610 is limited to designs with output rails of 48V. I can't find this specification on the component's datasheet, and am wondering where it comes from. Is this an absolute maximum rating? If the 60V rail isn't beyond a maximum, I would prefer to use the UCC28610 as the BOMs of the two modules could be fairly well aligned for much of the primary-side components.
