°, V
IN = 28V, IOUT = IMAX AMPS
2.
Derate power linearly to zero from 125
°C to 135°C.
3.
Regulation measured between pin 8 and pin 7.
4.
Recovery spec assumes that converter has been OFF for at least 500ms.
CAUTION:
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.
