    Looking for paper about soft start for buck regulator

    soft start who can give me another way that can use in integrated circuit ? Please help me! My goal of buck regulator is the soft_start time reach 10ms. And I think it's difficult. Who can help me?

    Swithing Regulation question

    Thanks inventor! My friend said "for most power MOSFETs the appoximation can be useful: Cgd=2*Crss1.sqrt(Vds1/Vdsoff)" Is he right? Added after 1 minutes: sorry, i mean Crss1 is Crss at Vds1(datasheet)

    Swithing Regulation question

    Thanks you! I have another question: How do I calculate Qgate of power MOSFET with Vds? Ex: Qg=4.5n with Vds=10v(datasheet) Qg=? with Vds=5.5v?
