Thermal Considerations

The power dissipation in the SC4215J is given by the fol-

lowing equation:

PD ≈ IO(VIN - VO)

The allowable power dissipation will be dependant upon

the thermal impedance achieved in the application. The

derating curve below is valid for the thermal impedance

specified in the Thermal Information section on page 3.
