Hi, 

My customer would like to evaluate the PMP21479 with fixed output 12V. Would you please guide how to adjust the output voltage to 12V in the PMP21479 design? Customer wants to evaluate the performance of ACF.

Best regards,

Randy

    Hi Randy, the easiest way is to just set the voltage divider for a fixed output.

    Make the following changes to the schematic

    R28 - Open

    R31 - 39.2K

    I am going to include the original designer here also incase I am missing something else.

    Thanks,

    Robert
