I am designing a PD system that operates on type 2 (25W) and requires system rails of 12V, 5V, 3.3V. I was curious if there is any reference design that would accomodate this. The PA1558 transformer has 3 parallel outputs of 11.2V, 5V, 3.3V...so this would be ideal to use. However, all the reference designs I find in TI PoE support documentation are for 5V and 3.3V output. How difficult would it be to adjust these designs to accomodate the PA1558?
