Notes:

(1)

Vin = 48Vdc, Ta = 25 °C, Airflow = 200 LFM for all data unless otherwise noted.

(2)

Output Ripple Voltage and noise is specified when measured with no external capacitance.

(3)

Transient response is specified without a capacitor at the output of the converter.

(4)

Thermal shutdown is monitored at the Thermal Measurement Location (TML). See ‘Mechanical Information’ on page 3 for TML

location.

(5)

See ‘Safety Considerations’ shown in Figure 1.

(6)

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 to

the unit)

(7)

Current share accuracy is optimized when the source and load impedance presented to each converter is equal.

(8)

Input Reflected Ripple is specified when measured with a 12uH source inductance.
