PRODUCTION DATA
Ensure that the output capacitance has enough ripple current rating to absorb the output switching ripple current. Equation 6 shows the output capacitor RMS current ICOUT calculation.
The output capacitor voltage ripple can be calculated as follows:
At certain input and output voltage and switching frequency, the voltage ripple can be reduced by increasing the output filter LC.
The charger device has internal loop compensation optimized for > 10-μF ceramic output capacitance. The preferred ceramic capacitor is 10-V rating, X7R or X5R.
