8.2.1.2.3 Output Capacitors
  1. Given a load transient deviation specification of 5% VOUT and a loop crossover frequency of 40kHz, use Equation 28 to estimate the output capacitance required for a 100% load step.
    Equation 28. C O U T ≥ ∆ I OUT 2 π × f C × ∆ V OUT = 6A 2 π × 40kHz × 0.25 = 96µF
  2. Noting the voltage coefficient of ceramic capacitors (where the effective capacitance decreases significantly with applied voltage), select four 47µF, 10V, X7S, 1210 ceramic output capacitors, which gives an effective capacitance of 30µF at 5VDC.
