Part Number: UCC28950

Hi team,

When output is shorted, customer power circuit enters into the burst mode.

Is this normal operation?

Customer wants to stop entering into a burst mode even when output is shorted.

Is it possible that UCC28950 be stopped to enter bust mode operation when output is shorted?

    Yoshwa,
    Thank you for the interest here please excuse the delay with the US holiday.
    Yes that is normal operation. Yes it can be changed by adding a pull-up resistor between SS and VREF so it will now operate in latch off mode and not hiccup mode. Please see page 30 of the datasheet for further details.
