SLPS327B September 2012 – April 2018 CSD86360Q5D
In the design example above, the estimated power loss of the CSD86360Q5D would increase to 3.84 W. In addition, the maximum allowable board and/or ambient temperature would have to decrease by 6.1°C. Figure 33 graphically shows how the SOA curve would be adjusted accordingly.
In the design example, the SOA temperature adjustment yields a reduction in allowable board/ambient temperature of 6.1°C. In the event the adjustment value is a negative number, subtracting the negative number would yield an increase in allowable board/ambient temperature.
