9.2.2.5 Output Capacitor Selection

Output capacitors are selected to meet the output ripple requirements and stabilize the votlage loop below V_BW(max).

To stabilize the loop below V_BW(max), evaluate the output impedance of available electrolytic and ceramic capacitors at the target voltage loop bandwidth frequency and combine capacitors in parallel to reduce the total output impedance of the capacitor bank below.

Equation 10.

Z_{O U T (V_{B W})} < \frac{C S A}{N \times V_{L O O P} \times V O U T_S C A L E_L O O P}

Equation 11.

Z_{O U T (V_{B W})} < \frac{6.155 m V / A}{1 \times 4 \times 0.5} = 3.0775 m Ω

Equation 12.

Z_{C_100 μ F} = \frac{1}{2 π f_{S W} C} = \frac{1}{2 π \times 58 k H z \times 9x100 μ F} = 3.05 m Ω

Equation 13.

Z_{C_330 μ F} = \frac{1}{2 π f_{S W} C} = \frac{1}{2 π \times 58 k H z \times 2x330 μ F} = 4.16 m Ω
