Notes:
1. Vin = 48Vdc, Ta = 20°C, Airflow = 200LFM unless otherwise noted.
2. Input Reflected Ripple Current is specified when measured with a 120µF 63V electrolytic capacitor across the
input pins.
3. Output Ripple Voltage is specified when measured with a 270µF electrolytic and a 10µF ceramic capacitor at the
converter output pins.
4. De-rating curves are conducted in a controlled environment. End application testing is required to ensure the hot
spot temperature is below the maximum specified.
5. Transient response is specified with 270µF electrolytic and 10µF ceramic at the converter output pins.
