43 / 56 page  10.4 Output capacitors selection Primary output capacitor As in a standard buck converter, the primary output capacitor is involved in: • Determining the output voltage ripple • Supporting load transient • Loop stability, by setting one pole and one zero in the transfer function Considering the output voltage ripple requirement, the primary output capacitance should be selected according to the following equation: COUT_pri= ΔIpri 8∙fSW∙ΔVOUT_pri−ESR∙ΔIpri (46) Normally, MLCC capacitors are the best choice for the output capacitor, therefore the ESR contribution is negligible and Eq. (46) can be simplified. Secondary output capacitor The secondary output capacitor supplies the secondary output load current during the tON (when diode D1 is reverse biased) and its value defines the secondary output voltage ripple (ΔVOUT). COUT_sec= IOUT_sec∙D ΔVOUT_sec∙fSW (47) L6983I Output capacitors selection DS14040 - Rev 1 page 43/56 |
