(2) Output Ripple Voltage and noise is specif ied 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 cont rolled 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 sour ce 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

Ordering Information

The EUS series of converters are certified to the standards listed in the ‘Standards Compliance’ section in the table above. If this product is built into information technology equipment, the installation must comply with the above standard. An external input fuse (10 A recommended), must be used to meet the above requirements. The output of the converter [Vo(+)/Vo(-)] is considered to remain within SELV limits when the input to the converter meets SELV or TNV- 2 requirements. The converters and materials meet UL 94V-0 flammability ratings. RoHS Compliant The EUS series of converters is in compliance with the European Union Directive 2002/95/EC (RoHS) with repsect to the following sustances: lead (Pb), mercury (Hg), cadmium (Cd), hexavalent chromium, polybrominated biphenyls (PBB) or polybrominated diphenyl ethers (PBDE).
