NOTES: 1. Unless otherwise stated: TC = 25°C, VIN = 28V, IOUT = IOUT MAX.
2. Derate power linearly to zero from 125°C to 135°C.
3. Regulation measured between pin 1 and pin 2 1/6" from case.
4. Recovery spec assumes that converter has been OFF for at least 500ms.
5. Input voltage can be increased to 12V to 50V at 5W output power.

CCAAUUTTIIOONN: The internal substrate contains beryllia (BeO). Do not break the seal. If accidentally broken, do not crush, machine, or
subject to temperatures in excess of 850°C to avoid generating toxic fumes.
