DESCRIPTION
The GS15T5-5.2 is a 15 W 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 swit chi ng) .
It offers short-circuit protection and input-output
isolation of 750V
minimum. The integral heatsi nk
DC
allows a large power handling capability and it
provides also an effective shielding to minimize
EMI.

USER NOTES
Thermal Characteristics
Worst ca se power dissipation at full load i s less than
5W.
T o operate the dev ice at an ambient temperat ure of
60 °C the therm al resi stance case-to- ambient m u st
be lower than 6.5 °C/W.
MTBF Calcul atio ns
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 T
amb
.= 40 °C
and forced ventilation of 100 feet/ mi nute.
This can be accomplished by adding an external
heatsink or by forced ventilation with air speed of
about 100 linear f eet/minute.
