7.4.2.1 Ripple Reduction

The high switching frequency of 400 kHz allows simple filtering. To reduce ripple, it is recommended that a minimum of 1-μF capacitor be used on the +VOUT pin. For dual output devices, decouple both of the outputs to the COM pin. The required 2.2-μF, low ESR ceramic input capacitor also helps reduce ripple and noise, (24-V input voltage versions require only 0.47 µF of input capacitance). See application report DC-to-DC Converter Noise Reduction.
