  • Hello,

    Pin3 and pin15 should not have eternal voltages added to them.

    The maximum voltage coming out of VREF pin 15 = 6.18V maximum.

    The UCC28065 uses a similar TSET current mirror and the maximum TSET voltage for this device is 7 V.

    The UCC28063 should be able to withstand the same voltage of 7 V.

    Regards,
