GS15T5-5.2
15 W DC-DC CONVERTER FOR ECL
Type GS15T5-5.2 Vin 5V Vout 5,2 V Iout 3A
DESCRIPTION The GS15T5-5.2 is a 15W DC-DC converter designed to provide a 5.2V isolated output from a 5V input. The device can operate with an output current in the range of 0.0 to 3.0A without any intermittent operation (packet switching). It offers short-circuit protection and input-output isolation of 750VDC minimum. The integral heatsink allows a large power handling capability and it provides also an effective shielding to minimize EMI. ELECTRICAL CHARACTERISTICS (Tamb.= 25 C unless otherwise specified)

USER NOTES Thermal Characteristics Worst case power dissipation at full load is less than 5W. To operate the device at an ambient temperature of 60 C the thermal resistance case-to-ambient must be lower than 6.5 C/W. This can be accomplished by adding an external heatsink or by forced ventilation with air speed of about 100 linear feet/minute.
MTBF Calculations The MTBF according to MIL HDBK-217E calculation for a ground benign environment is: - 216k hours for a case temperature of 91 C. - 379k hours for a case temperature of 60 C. This last condition can be obtained at Tamb.= 40 C and forced ventilation of 100 feet/minute.
