  • RE: LM25116: DC/DC(LM25116) Block auto shutdown : VCC pin of DC/DC abnormal voltage detect

    Resolved
    Hello Kwangsug I think there is a misunderstanding. CSD18514Q5A is 4-6mOhm, 29nC @ 10V MOSFET. CSD18504Q5A is 6=10mOhm , 15nC @ 10V MOSFET. You can use the same MOSFETs on both high- and low-side, but usually engineers select higher Rdson & lower Qg MOSFET…

  • RE: LM25149: Webench can't define own MOS spec

    Resolved
    Switching losses at 500kHz obviously...your gate charge values are huge. For a 24V to 3.3V conversion, the Rdson can be higher (given the low duty cycle), resulting in lower Qg. Choose a 40V FET such as the CSD18504Q5A. Qg at Vgs = 5V is 8nC and Qgd/Qgs…

  • RE: PSpice for TI: error Name on .ENDS does not match .SUBCKT

    Resolved
    Hi Jackie, I changed the part from CSD18504Q5A to CSD18537NQ5A and the problem went away. Now I can start looking into running the simulation. You guys should probably look into that SPICE model. Cheers,
