  • UCC28C41: Boost converter with no load not giving designed output voltage

    TI Thinks Resolved
    Part Number: UCC28C41 Hi all, I am testing the above boost converter with input of 15V and output should be 20V. But I am getting 17.2V only at output without load. Please help me to fix the issue. Feedback resistors values are also given above. Thanks…

  • UCC28C41: Boost converter with no load not giving designed output voltage

    TI Thinks Resolved
    Part Number: UCC28C41 Hi all, I tested with load also (0.5A). But still voltage is still reduced. that means with load: Vin=15V, ILOAD=0.5A Vout=16V Without load: Vin=15V Vout=17.5V I probed the Vref pin. There are noises coupled at Vref pin so that…

  • RE: UCC38C41: Performance outside of temperature range

    Hi, Yes, the die is the same between UCC38C41 and UCC28C1. At production, screen out UCC28C41 on wider temperature range. Then test UCC38C41 on narrow temperature range. But there are no tests for UCC28C41 with temperature range between 70C and 80C.

  • RE: PSPICE-FOR-TI: UCC28C44 simulation from Webench power designer failed

    Hi, It looks even better you can use UCC28C41 transient ref design to make simulation.. UCC28C44 has only difference on UVLO compared to UCC28C41. Actually UCC28C44 model is changed from UCC28C41 only on UVLO. These models have unencrypted version so…
