  • LM21215: Can a control system with positive phase margin and NEGATIVE gain margin?

    Resolved
    Part Number: LM21215 Hi Team, As we know, generally speaking, the premise of a stable system is that about 45° phase margin and 10dB gain margin. I noticed about some system is still stable even if when -180° with a negative gain margin. Why does system…

  • SM320C6678-HIREL: Lm10011 + LM21215

    TI Thinks Resolved
    Part Number: SM320C6678-HIREL Other Parts Discussed in Thread: LM10011 Is it mandatory to set CVDD start up voltage to 1.1V, Because as per my current design Rset=301k, Rfb1=8.45k, Rfb2=10k So theoretically calculated CVDD= 1.107 - 0.000507 = 1.106V. …

  • LM21215: wrong formula for fz2

    Resolved
    Hi! I think (as per my calculation) the equation 16 for fz2 on page 21 not correct. There should be Rc2 instead of Rc1 i.e. fz2 =1/[2.pi .(RC2 + RFB1).CC3]. and the fp2 can be simplified to 1/[2.pi.RC1 CC2) because Cc1 >>Cc2 regards Bishnu
