Power Dissipation and Junction Temperature (continued)

TJ = TA + ((IOUT

2 × R

DS(ON)) × θJA)

where

•

IOUT = rated OUT pin current (A)

•

RDS(ON) = Power switch ON-resistance at an assumed TJ (Ω)

•

TA = Maximum ambient temperature (°C)

•

TJ = Maximum junction temperature (°C)

•

θJA = Thermal resistance (°C/W)

(1)

If the calculated TJ is substantially different from the original assumption, estimate a new value of RDS(ON) using

the typical characteristic plot and recalculate.

If the resulting TJ is not less than 125°C, try a PCB construction or a package with lower θJA.
