36 / 68 page ![]() The sampling effect contribution FH(s) is: FH(s)= 1 1+ s ωn⋅Qp+S2ωn2 (22) where: ωn=π⋅fSW Qp= 1 π⋅[mc⋅(1−D)−0.5] (23) 5.2 Error amplifier compensation network The typical compensation network required to stabilize the system is shown in Figure 36. Transconductance embedded error amplifier: Figure 36. Transconductance embedded error amplifier RC and CC introduce a pole and a zero in the open loop gain. CP does not significantly affect system stability but it is useful to reduce the noise at the output of the error amplifier. The transfer function of the error amplifier and its compensation network is: A0(s)= AV0⋅(1+s⋅RC⋅Cc) s2⋅R0⋅(C0+Cp)⋅RC⋅Cc+s⋅(R0⋅Cc+R0⋅(C0+Cp)+Rc⋅Cc)+1 (24) Where Avo = Gm · Ro The poles of this transfer function are (if Cc >> C0 + CP): fPLF= 1 2⋅π⋅R0⋅Cc (25) fPHF= 1 2⋅π⋅R0⋅(C0+Cp) (26) L6986H Error amplifier compensation network DS12905 - Rev 2 page 36/68 |
