UCC28C53-Q1: Short-circuit current 55mA

Part Number: UCC28C53-Q1

Dear Team,

Could you pls confirm that UCC28C5xx has the short ciruit protection? I can see that there is short-circuit pera in the VREF desc. pls elobrate more on this. Also it would be appricicated if you  advise on how can we implement the Short-Circuit protection in the Flyback circuit. 

  • Hi Manoj,

    The 55mA Short-circuit current limit is for the Vref pin. not the output. The current limit is set on the primary side with the RCS resistor as shown below:

    I hope this answers your question.
