TPS43060: The output ripple

Eric Mo

Part Number: TPS43060


Hi Team,

My customer is debugging the TPS43060  chip and found a large ripple output (No load around 90 mV), Please find schematic diagram of the TPS43060   attached. Do you have advice for this issue?

Best regards,

    Hi Eric,

    This seems running into the min duty cycle.  Adding a dummy load should help.  Actually the ripple is not that big on top of a 48V voltage rail, which is smaller than 1%, and the customer seems overconcerned about the ripple.

    Thanks,
