If the ripple is great enough (at least 20mV), the compensation network simply consists of a CINT capacitor. Figure 21. Integrative compensation The stability of the system firstly depends on the output capacitor zero frequency. It must be verified that: Equation 49 where k is a free design parameter greater than unity (k > 3) . It determines the minimum integrator capacitor value CINT: Equation 50 If the ripple on the COMP pin is greater than the integrator output dynamic (150mV), an additional capacitor Cfilt could be added in order to reduce its amplitude. If q is the desired attenuation factor of the output ripple, select: CFILT CINT RINT gm + - VREF VSNS Ton One-shot generator Vr=0.9 V PWM Comparator + - COMP VOUT Integrator out out Zout SW C R 2 k f k f ⋅ π = ⋅ > Vo Vref f k f 2 g C Zout SW m INT ⋅ ⎟ ⎠ ⎞ ⎜ ⎝ ⎛ − ⋅ π > |
