UCC28C43-EP: UCC28C43-EP

Part Number: UCC28C43-EP


Оur device worked without problems when we used UCC28C43DR.
We are use UCC28C43MDREP now PWM controller is burn. The VDD and GND pins are getting shorted.

  • Hi Dugin,

    1. UCC28C43DR is the commercial version of the part thus lower temperature rated part ( -40C to 105C)
    2. UCC28C43MDREP is enhanced performance thus the part is characterized to higher temp range ( - 55C to 125C)
    As a result UCC28C43MDREP ( UCC28C43-EP) electrical specs would be updated to reflect the performance. Otherwise from silicon/ die the two parts would be the same.
    3. Are you seeing multiple failures or is it a random failure.
    4. Have you eliminated the obvious issues i.e. assembly / soldering/ esd
