PowerPAD 100-pin TQFP package
The TFP501 is packaged in TI’s thermally enhanced PowerPAD 100-pin TQFP packaging. The PowerPAD
package is a 14 mm
× 14 mm × 1 mm 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 100-pin TQFP PowerPAD package offers a backside solder plane that connects directly
to the die mount pad for enhanced thermal conduction. Soldering the backside of the TFP501 to the application
board is not required thermally, as the device power dissipation is well within the package capability when not
soldered.
Soldering the backside of the device to the PCB ground plane is recommended for electrical considerations.
Since the die pad is electrically connected to the chip substrate and hence chip ground, connection of the
PowerPAD back side to a PCB ground plane helps to improve EMI, ground bounce, and power supply noise
performance.
The following table outlines the thermal properties of the TI 100-pin TQFP PowerPAD package. The 100-pin
TQFP non-PowerPAD package is included only for reference.
