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.

* 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.

All specifications are typical at nominal input, full load, and 25DegC unless

otherwise noted

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.
