Case: RTHJC
2144C–BDC–04/03
The following table lists the converter thermal performance parameters of the device itself,
with no external heatsink added.
Table 9. Thermal Resitance
Figure 48. Thermal Resistance from Junction to Ambient: RTHJA
Typical value for Rthjc is given to 6.7 C/W (8 C/W max).
This value does not include thermal contact resistance between package and external compo-
nent (heatsink or PCBoard).
As an example, 2.0 C/W can be taken for 50 µm of thermal grease.
