  • UCC28C41-Q1: UVLO options

    Part Number: UCC28C41-Q1 Hi team, Customer would like to know whether we have p2p product of UCC28C4X-Q1 with lower UVLO (<6.5V) ? Or if there's work around method of external circuit to reduce UVLO value? Thanks, Scarlett

  • UCC28C41: ucc28c41 comp pin output current limit

    TI Thinks Resolved
    Part Number: UCC28C41 Hi team, UCC28C41 has a comp pin for EA output. In datasheet, it is current limit internally, could you share the value of the limit point? or maybe a curve can show the limit performance? Thanks Michael

  • RE: UCC28C41: Model file for simulation

    Hi Vijay, If you want to use the PSpice model for the device in Altium, please download the unencrypted PSpice model from the product folder. You will then have to follow the Altium instructions for how to install a PSpice model. You will still have…

  • RE: UCC28C41-Q1: Differences in UCC28C4X_ duty cycle and UVLO

    Hi Cao, Both of UCC28C41 and 28C40 can support HV input applications. For duty cycle limitation . It only related to input voltage range , for narrow range input , the 50% max. duty cycle can meet output regulation and it can brings some benefits…
