Thermal Resistance
from Junction to
Ambient: RTHJA
The following table lists the converter thermal performance parameters of the device itself,
with no external heatsink added.
Figure 48. Thermal Resistance from Junction to Ambient: RTHJA
Thermal Resistance
from Junction to
Case: RTHJC
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 m of thermal grease.
