Hi team,

May I know if customer would like modify TPS24755EVM to 5Voutput, can customer just change R16/R21 value? or other components also need to change?

Thanks & regards

Hi Eddie,

The TPS23755 is not optimized for a 5V output. It is intended for 12V diode rectified designs. Instead, we recommend our 5V/2.3A PMP9175 design.

In addition to changing that voltage divider ratio, the transformer would need to be changed for the appropriate turns ratio for 5Vout.

Thanks,
