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. DHC2803S IOUT MAX = 2.0ADC when voltage is adjusted to 3.0Vdc, VIN = 13-50Vdc, and CLOAD = 100µF.
6. DHC2803S POUT MAX = 6W when VIN = 13-50Vdc
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.
