Other Parts Discussed in Thread: PMP9563
I have referred to two design below.
EVM-383 http://www.ti.com/lit/ug/slvu304c/slvu304c.pdf
PMP9563 http://www.ti.com/tool/pmp9563?keyMatch=PMP9563&tisearch=Search-EN-Everything
PoE / Forward topology / 12V 30W output
Can I use MOSFET of 60V Vds to replace Q5 in EVM-383 ? (Also Q6 in PMP9563)
I measured its Vds with full load output, the pk-pk voltage is under 40V.
Why does PMP9563 use 100V Vds MOSFET?
