FUNCTIONAL DEVICE OPERATION
PERFORMANCE
PERFORMANCE
The 33886 is designed for enhanced thermal performance.
The significant feature of this device is the exposed copper
pad on which the power die is soldered. This pad is soldered
on a PCB to provide heat flow to ambient and also to provide
thermal capacitance. The more copper area on the PCB, the
better the power dissipation and transient behavior will be.
Example Characterization on a double-sided PCB: bottom
side area of copper is 7.8 cm 2 ; top surface is 2.7 cm 2 (see
Figure 21 ); grid array of 24 vias 0.3 mm in diameter.
Figure 22 shows the thermal response with the device
soldered on to the test PCB described in Figure 21 .
