Notes:
Vin = 48Vdc, Ta = 25 °C, Airflow = 200 LFM for all data unless otherwise noted.
Output ripple voltage and noise is specified when measured with a 10uF tantalum and a 1uF ceramic capacitor at the converter output pins.
Transient response is specified without a capacitor at the output of the converter.
Product operates with an external capacitance significantly greater than specified. However, for values higher than 2000uF please contact
C&D representative.
Thermal shutdown is monitored at the Thermal Measurement Location (TML). See ‘Mechanical Information’ on page 3 for TML location.
See ‘Safety Considerations’ shown on last page.
De-rating curves are conducted in a controlled environment. End application testing is required to ensure the Thermal Measurement
Location temperature is below the maximum specified.
Recommended airflow direction is from pin 1 to pin 3, or 3 to 1 (transverse airflow).
Current share accuracy is optimized when the source and load impedance presented to each converter is equal.
Input Reflected Ripple is specified when measured with a 12uH source inductance.
