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 a 10uF tantalum and a 1uF ceramic capacitor at the converter

output pins.

(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.

(7)

Recommended airflow direction is from pin 1 to pin 3, or 3 to 1 (transverse).

(8)

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

(9)

Input Reflected Ripple is specified when measured with a 12uH source inductance. Without an input filter inductor, input ripple is less

than 1 Arms for an input filter capacitance rated 70 mohms esr
