WebThe exposed pad can be soldered to the PCB so that the heat can be driven off directly (the JA is only half as much as the standard L(T)QFP). Besides, this pad is also electrically grounded, and thus results in far smaller ground inductance. Exposed pad L(T)QFP is a cost-effective solution suitable for enhancing thermal and electrical performance.
