Tool/software:
TPS561201 is D-CAP2 mode of control . I want to do stability analysis to understand the phase margin and gain margin of the design.
I want the ripple rejection parameters and ToN (One short) to calculate the transfer function Gopen-DCAP2(s)=Gdv(s)Hd(s)(1+sTc) (Acp /Vin) HFB(s) .?
Design Parameters
Vin =13V, Vout =5.5V, L=3.3uH, Iout =1A and Cout =64uF
During our test, it is observed that, whenever load current is increased to 0.6 A (60%), there is sudden spikes in the Inductor current. Want to understand why this is happening and stability analysis of the D-CAP2 control method?.
