Nominal CQFP68
Thermal
Characteristics
Although the power dissipation is low for this performance, the use of a heat sink is
mandatory.
The user will find some advice on this topics below.
Thermal Resistance
from Junction to
Ambient: RTHJA
The following table lists the converter thermal performance parameters, with or without
heatsink.
For the following measurements, a 50 x 50 x 16 mm heatsink has been used (see Figure 51
Note:
1. Heatsink is glued to backside of package or screwed and pressed with thermal grease.
