Note:
1. Ripple and noise are measured at full load, 20 MHz BW with 10µF tantalum capacitor and 1µF ceramic capacitor across output. The 48 Vdc output models require a 10uF
aluminum capacitor and 1uF ceramic capacitor across the output.
2. An external input capacitor of 470μF for 24 Vdc input models and 47μF for 48 Vdc input models is recommended to reduce input ripple voltage.

Notes:
1. For the 28 Vdc output models, a minimum input voltage of 10.8 Vdc is required to trim the 24 Vdc input models up 10%, and a minimum input voltage of 19 Vdc is
required to trim the 48 Vdc input models up 10%.
2. All specifications are measured at Ta=25°C, nominal input voltage and full output load unless otherwise specified.
