Notes:
48Vdc, Airflow data unless otherwise noted. Output Ripple Voltage noise specified when measured with 10uF tantalum ceramic capacitor converter output pins. Transient response specified without capacitor output converter. Thermal shutdown monitored Thermal Measurement Location (TML). `Mechanical Information' page location. `Safety Considerations' shown Figure De-rating curves conducted controlled environment. application testing required ensure Thermal Measurement Location temperature below maximum specified. Recommended airflow direction from (transverse). Current share accuracy optimized when source load impedance presented each converter equal. Input Reflected Ripple specified when measured with 12uH source inductance. Without input filter inductor, input ripple less than Arms input filter capacitance rated mohms
