NOTES
1. Starting the Product into a Short Circuit Mode will damage the device.
2. In order to meet all specifications for the 3.3Vin models, an external capacitor
is needed on the input. The capacitor is SANYO OS-CON,SA-Series, 68uF/10V.
3. BELLCORE TR-NWT-000332. Case 1: 50% Stress, Temperature at 40DegC.
(Ground fixed and controlled environment)
4. Maximum value at nominal input voltage and full load.
5. Minimum value at nominal input voltage and full load.
All specifications are typical at nominal input, full load, and 25DegC unless
otherwise noted
*
These are stress ratings. Exposure of the devices to any of these conditions
may adversely affect long term reliability. Proper operation under conditions
other than the standard operating conditions is neither warranteed nor implied.
Astrodyne products are not authorized or warranteed for use
as critical components in life support systems, equipment used
in hazardous environments, nuclear controls systems, or other
mission-critical applications.
