Part Number: TPS2373-4EVM-758
Other Parts Discussed in Thread: TPS2373, PMP21318,

Hi Team,

Our customer try to modify TPS2373 EVM from 5V to 12V by changed transformer (spec. as attached) and resistor divider. but no output voltage, customer can measure +54V from VDD. 

Would you help to check what eles we need noticed if customer modify our EVM board to +12V output?

Thanks & Regards

Eddie
