PowerPAD
64TQFP package
The TFP6422/6424 is packaged in TIs thermally enhanced PowerPAD 64TQFP packaging. The PowerPAD
package is a 10 mm x 10 mm x 1.4mm TQFP outline with 0.5mm lead-pitch. The PowerPAD
package has a
specially designed die mount pad that offers improved thermal capability over typical TQFP packages of the
same outline. The TI 64TQFP PowerPAD
package offers a backside solder plane that connects directly to the
die mount pad for enhanced thermal conduction. The system designer has the option to solder this backside
plane to a thermal/ ground plane on the PCB. Since the die pad is electrically connected to the TFP6422/6424
chip substrate and hence ground, the backside PowerPAD
connection to a PCB ground plane can improve
ground bounce and power supply noise.
The connection of the PowerPAD
to a PCB thermal/ground plane is purely optional.
The following table outlines the thermal properties of the TI 64-TQFP PowerPAD
package. The 64-TQFP
non-PowerPAD
package is included only for reference.
