Part Number: UCC28019A

Hi Team,

To replace ICE2PCS02, I think UCC28019A can not replace it BOM to BOM, could TI share that what parts needs to be modified?

Thank you.

Best regards,

C.T.

  • Hello C.T.

    The UCC28019A and the ICE2PCS02 are pin for pin compatible but since no competitive parts are plug in replaceable the user should expect  
    the user should expect to make slight component value changes in order to achieve the design requirements.

    As regards these two pfc controllers, the ICE2PCS02 has a peak overcurrent limit (PCL) of -1.04V and a soft overcurrent limit of -0.68V.
    The UCC28019A has a PCL of -1.08V and a SOC of -0.73V.
    Also the ICE2PCS02 has a slightly lower brownout turn on point of 0.71V compared to the 0.82V for the UCC28019A

    These are the most significant differences between these two parts.

    Regards

    John
