DESCRIPTION
The GS15T5-5.2 is a 15W DC-DC converter de-
signed 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 of750V minimum. The integralheatsink
DC
allows a large power handling capability and it
provides also an effective shielding to minimize
EMI.

USER NOTES
MTBF Calculations
Thermal Characteristics
The MTBF according to MIL HDBK-217E calcula-
tion for a ground benign environment is:
Worst casepower dissipation at full loadis less than
5W.
- 216k hours for a case temperature of 91 °C.
- 379k hours for a case temperature of 60 °C.
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 last condition can be obtained at T
.= 40 °C
amb
and forced ventilation of 100 feet/minute.
This can be accomplished by adding an external
heatsink or by forced ventilation with air speed of
about 100 linear feet/minute.
