I’m trying to adjust the EV8008’s reference circuit so that the output is 5V.
I am using the Wurth 750310744 transformer, and I adjusted the voltage divider resistor in the feedback circuit, however I am not getting the right voltage out.
The two resistors (R24 & R25 in my schematic) are now both 191k, however the output voltage I’m reading is 8.4V instead of 5V.
I measured the reference voltage output by the TL431 and it’s correct (2.5V).
Is there anything I need to change in the circuit?
Any help would be greatly appreciated.
