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 40°C. (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 25°C 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.
