Hi,
I have a circuit based on TI ref design (UCC28700DBVT) using custom fly-back transformer.
The transformer was supposed to deliver 5V@4.2A,
Having constructed the prototyping board I could not get the maximum output.
I wonder if someone could point out what I am doing wrong.
Not sure if the circuit or the transformer itself.
I've attached here the schematic and the transformer spec.
Thanks.
